ProComp/Speedmaster aluminum heads

8553 Felpro

Those are what my oldest son has on his 360. It is 11:1 with eddy heads. He decked his block so the pistons were .015 out of the hole. Although they are considered a cheap gasket He has had no problems. He put that motor together when he was 18, an he is 25 now. Motor is in his only car. driven daily.
Well I'm one hundred percent convinced! If that gasket can hold back what an eighteen-year-old can give to it.. I'm sold...
