Build suggestions for 340?

Opened them up to 2.05 from 2.02. Block has been bored .30 over. The rotating assembly is pretty well stock. 10.8 compression. It really likes the 96-98 octane fuel. Has good street manors too. I didn’t go with aluminum heads, cause I wanted to keep it as period correct as possible.
totally understood! How did you achieve 10.8 compression even with the factory dome style piston I found true compression to always hang right around 10 to 1 with a 75cc chamber. I guess you milled them quite a bit?
