I did't mean for this to happen. I got a good deal on this short block. so I bought it. He told me it had 12.5 to 1 with his 75cc heads. LOL wrong ! and it had small domes on it. so now I am try to do the best I can with what I got.




Your thinking is correct, that if you optimize this combination you will likely be over the limit of a stock block unless you go easy. But going easy is tough to do when you want to see what it can do.
Why not take the domes off and rebalance?
