    Last night I was reading the 1986 edition of "Ford High Performance", which was written by Ford Special Vehicles Operations of the day, and published by Petersen Publishing.
    It has an interesting story of a buildup of a performance CVH engine, which used the special SVO "M-6049-B111" cylinder head, which is referred to as "the European Head".

    As of this writing, there is not a single record of "M-6049-B111" on the entire Google universe, so I am wondering if anyone has ever seen this head, and can advise me what the actual casting number on it is. Was it a regular production head used somewhere in Europe? I may get one of my in-law European relatives to look for one if I can find out more.

    The 1986 SVO head says this head has 20% more flow than "domestic production heads", whatever those are, possibly 1.6 hemi heads?

    I tried searching the Burton Power site and ebay in Britain and Germany, but did not find answers. I did discover that there was a 1.8 CVH that a few sellers were offering hydraulic roller lifters for, but annoyingly, I could not find a matching roller camshaft.

    That head is not much different than any 1.6 CVH head with an "E3EE" suffix. You could make an older head (E1EE suffix) the same with a bit of porting.

    There is no "magic" in it, unlike the higher compression forged pistons, forged crankshaft and mechanical cams also available in such catalogs.

    The UK guys pretty much loved the 1.6L, and a bit of the 1.3l, too, but ignored the 1.8L, which was a revised version, sharing more in common with the US 1.9L. To my knowledge, and based on specs, the UK 1.6L head swaps over to the US 1.6 or 1.9 block.

    With all that said, by the time the mid 80s rolled out, the US had switched to the 1.9L, which (unless it was the HO engine) used a heart-shaped "High swirl" chamber. Late 80s saw the switch to the leanburn "D" shape. The exhaust ports shrank, and the intake ports improved for the HO head, while everything shrank for the non-HO heads. However, just about any 1.6L head can be ported on the intake side to match or better the 1.9L HO port volume, but I would not be surprised if they outflowed the non-HO 1.9L heads in stock form. The leanburn 1.9L had the smallest intake ports.

    The upside is that UK cams will fit the 1.6L head, and slightly larger valves can be fitted (intake only, IMO). Those changes could easily account for 20% better flow. For all we know those mysterious part numbers were an off-the-shelf piece that used a hotter cam.

    The other neat part from the UK is the T3 flanged turbo manifold. The US got a smaller flange.

    No, the book you pictured is not the one I read, although it does look like a good reference. This is the one I am referring to:

    Here is the image and description of the "European" aka EAO cylinder head. The SVO catalog, and the buildup article in the book describe it as fitting the US engine.

    That's what I'm trying to do, by enlisting the help of the FEOA fraternity.

    This is interesting! Not a promising quest but I love having proof the C.V.H. engines existed in publishing.

    All the parts existed at one time (early 1980s) in the Ford motorsports catalogs for the 1.6 CVH. Unfortunately, that is pushing 40 years ago.

    I have a NIB forged crank and a NIB solid lifter cam (with NIB mechanical lifters) as well as several NIB high-performance hydraulic cams and boxes of NIB anti-pump-up lifters.
    You find this stuff from time to time on ebay...but you need to search via the part numbers in the catalog.

    It is not that expensive a collection, but took years to collect.

    Trust me when I tell you I would not hunt the cylinder head since 1983 stock heads are just as good.

    As for pistons, I always used 1.3 pistons from the UK in my 1.6 motors because those gave you an 11 to 1 compression with a 1.6 crank--piston pin heights and the stroke accomplished this.

    Where did you get that? I have a 1984 EXP Turbo that I'm resto-modding, I picked up a professionally-rebuilt 1.9 CVH converted to turbo with the 1.6 SVO engine's accessories.
    I'm slowly sourcing out performance parts to get some awesome power out of it and I'd really like to know more about SVO's hand in the engine.

    Can you share all the sections in that magazine that include the 1.6?

    Are you referring to this book I posted the picture of?

    [​IMG]

    If so, I picked that up many years ago at a swap meet or book store, in pre-interweb days.

    It's got a small section on the CVH engine, but I don't have a scanner or suchlike to copy that.

    How about a picture of your project? It sounds interesting.

    Okay, yep that's the one.

    Here's my collection, almost have the top left EXP restored, the Turbo is the black EXP just below right of center.

    My EXP Turbo is pretty rough underneath but has great bodywork, it has 98,000ish miles on it spending it's whole life in Wisconsin. Somewhere down the line someone removed and bypassed the turbocharger, I can't confirm if it runs but it turns over without any issues.
    The 1.9 I mentioned was built up to replace someone else's 1.6 Turbo but the guy never got to do more than test run it before his car rotted out. It still uses the 1.6 head, valve cover, oil cooler, turbocharger, intake man., exhaust man., etc. The only differences are the block and crank, I don't know what pistons, rods, cam, or injectors are in it though.... Someone also added "N-S" lifters (can't remember if they're hydraulic or solid).

    Yeah I've seen his on Facebook, I can't afford another car right now even if I had the space for it. He also doesn't have much of an interior, and that's something I'm short on as they're rather rare....

    I have a rust-free 1983 body that's been gutted already, I just need to pull the engine and start swapping over the Turbo's parts. I'll start the project when I finish my convertible's restoration :)

    Hey Joeg, where have you been finding those 1.3 pistons? I got a couple 1.6 HOs which are the taller pistons (9:1 instead of 8.5:1) but want more compression.

    I'm also curious what exact differences there are between the EAO head, the Turbo head, the 81-82 head and the 83-85 head - which you said was the same as the EAO?

    Yeah I've read through most of it a few times, very good research but his findings on the Turbo heads don't seem congruent with what Ford and others had said about them and I'd like to know how the different Euro heads compare too.

    Can you send a link to the Ford literature? I am interested to see what it has to say that is different, or additional, to what Scortster wrote in his posts.

    Some of it is in the above photos, Ford says the "EAO head" flows 20% better than our domestic (lets assume 1.6L) heads. But it doesn't specify which Euro heads, might just be Ford's best head that was offered over there at the time - whichever one it was.

    I can't remember where I read it but Ford had stated somewhere that the North American 1.6 Turbo head was the SVO head and was comparable performance-wise to the otherwise superior Euro heads. I'll have to compare part numbers because maybe the Turbo/SVO head is just their Euro ("EAO") head with different seats as the UK wouldn't ban lead-fuel until the 90s.

    This would mean the the Turbo head is the most superior of our domestic 1.6 heads, but "scortster" ropes the North American Turbo head in with all the other 83-85 heads. The port openings may be the same size but I thought the turbo heads had better flowing ports, maybe I'm mistaken and only the SVO/Motorsports heads are like that (part #M-6049-........).

    Everything else in his report is spot on, I'd just like to know more about the "performance" heads that didn't come on any production cars and the Euro heads. Of course, and how all they stack up with the heads we know now. That would make for a giant write-up but would be quite worth it!
