max compression on pump gas\steel cylinder head\241 @ 50 cam

Ya i think its about .040 maybe a tad more if i remember right, the big drop in cc was when i replaced the stock valves with Milodon street valves, they dont have the concaved dish under them and are of a fairly thick margin.


Hmmm, that is good to know!

(now why did I forget to water that money tree of mine)
