Hey Fellas,

Kind of new here but not new around engines...if any of you have ported heads from the 1.8 dohc (out of a 1992 escort gt) not sure if casting changed at any time.

But if you have ported the head can you tell me where any thin spots I might want to stay away from? it would save me buying a head which I would then fillet on my band saw.

I will be using single cut carbide, Sanding rolls and emory.

Also for valve swaps I want to go bigger valves , with a three way valve grind, valves with 32degree cut back, remove any shrouding around valve and cc and polishing the combustion chambers. I am building a NA engine for canyon running against 1.8 VW rabbits

The search button didn't yield any spec stuff just general info.

Thanks in advance fellas

I can send you pics of mine. As for larger valves you won't gain as much. Better to back cut, de shroud, and bowl blend. I had mine done on a flow bench months ago and still have yet to run it. Send me a PM of your email.
