RE: HEAD cc????
Why not buy the heads if they are a great deal, and take them to a machine shop and have them shaved. c/r is a major player in power. I think when I was in the process of building my engine, the shop had a computer program for HP/TQ. The difference between 10:1, and 10.5:1 was almost 35 HP/45 TQ. I went with 10.5:1. According to most books that I have read, 11.8:1 is as far as you want to go with pump gas. I'm also going the nitrous route, and wanted to stay more streetable.
