help with pistons i have a 96' GM crate 454 stock. this engine pulled a valve seat at around 8,000 miles and all i have done to it is had the valve seat replaced and the block and heads dipped/checked and installed new valves and springs to go with my cam. What i want to know is can i run a set of stock ls6 .095 domed pistons in this engine and will this improve the perfomance of my build as oposed to flat tops, here is the cam i am using
Comp Cams CL11-207-3
Thanks in advance

Whats the specs on the heads?
Need to know combustion chamber cc, and intake port size (or at least the shape--small oval, large oval, etc)
Need to know this to figure dynamic compression with the cam you posted.

the casting on the heads is 10114156, they are oval port and according to all i can find 118cc, however, every page i have found on these heads say they are an open chamber head and they are not. these are a closed chamber with only enough for the valve recess. as far as small or large ovals, i really don't know how to tell the difference.

So do not put dome top pistons under those heads, you might be one of very few who have tried only to realize it doesn't work.
Your best bet is to increase compression by using heads with a smaller chamber and bigger ports and leaving the bottom end alone.
