For a little more you can get a custom piston with the correct dish for what ever head you want to run.I just did 2 428s with Autotec pistons.Tom

Yep those are different for sure.
I haven't seen the combustion champers on a 670 head in a long time, but the 13's I used for that combo don't have much quench area. In fact most of the quench is around the parameter of the chamber as you can see in this picture. So I didn't need a fancy "D" shaped dish to take advantage of a big flat area, these heads didn't have enough of that to worry about. In fact the ring I created with the bowl style dish was wide enough to take advantage of most all of it. Plus I could create the CC needed with the added area instead of making a smaller D shape deeper to gain CC and possibly making the piston weaker, there is only so much meat to work with. |

FJ
I am about to cc my first combustion chamber. Do I need to put anything down to seal the plexiglas to the head, or just let it lay flat?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
