I've decided to rebuild my 2f, I'm going to use all oem other than the pistons and cam. I've got the pistons lined up already, forged flatops. I guess the question is RV cam? Where do I source a good one other than MAF? I went back 20 pages and read up old posts on the subject, and other than decking the head, any other little tricks to do while this thing is apart? Cruiser parts has "high compression" heads, would that be a better way to go? What's the diff between a HC head and a decked factory 78?
