I concur with Patrick on the Wiseco pistons, they seem to be nice, although JE pistons have a good reputation as well. I also agree with him on the chance that 11:1 might be pushing it a bit with 93 octane gas. Probably want to consider 10.5:1. With the head milling I am running 12.7:1 and using 110-112 octane race fuel. 11:1 is not that far below where I am at to drop from 110-93 octane in my humble opinion.
