RE: taking my heads to the machine shop
no shop will go past .030, youll destroy them.
Might wanna consider that and a thinner head gasket. Not much you can do, most compression is withing the piston construction.

RE: taking my heads to the machine shop
you cannot get GT40 heads to run that high compression... you would have to take off WAY too much material.
remember... if the machine shop mills them any further than .025"... your gonna need toget shorter pushrods
only GT40P heads can get you close to 10:1 on a stock stang bottom end

RE: taking my heads to the machine shop
i have 351w heads and the machine shop told me they were 60cc and they are 68cc, so they want to flat mill them. insteed of refunding my money. so is there anyway i can get 10:1 compression with out shorter pushrods and messing with the intake bolt holes. i have flat top kieth blacks that are 3 thousandths in the hole.
