Well, this summer my engine is going to have to go under some major development. It is satrting to blow oil quite a bit, mostly during downshifts. So while the head is apart I was thinking of swapping in all the late model Miata Valvetrain(Cams, solid lifters, springs etc). Now if the smoking is not comng from valve seals, then it looks like I have to take the head off to chang the piston rings. I just replaced the head gasket last summer, Can I reuse this gasket, or am I going to have to get a new one? What is needed to swap in the Higher compression Miata pistons, since there is different amount of wear on my engine, and the newer pistons?
