The heads have been resurfaced. No I havent cc'd them. Heres the question now-Do I use flat tops and mill the block .025 to have a maximum of 9.8:1 ratio. Or do I leave the block alone and use 4cc domes(these pistons are over $300 more). Compression would be at or a little over 11:1. Would pump gas do the job?
