Here is a listing of all head castings. Even though they may be listed as closed and open chamber heads, there were variations in chamber size. The smallest closed chamber heads were like 98cc and the largest closed chamber heads were about 108. Then they got into semi open that were about 113 and then true open chamber heads were 118-119.
Ok guys new question?? And I just want an educated guess 206 heads on my basically stock bottom end with the stock dished pistons what will my approximate compression ratio be? Also with that set up a performer intake and comp cams Xtreme Energy 11-238-3 what is your best guess on horsepower and torque? I know it's much more technical than that but a guess would be cool thanks again guys
Good that's what I was shooting for the cam works best with under 9.5 and it being a work truck I want to be able to run pump crap. It may get a set of headers to I have a set but I don't know what there for
