302 heads

Whoa! I didn't know the KBs cost that much! I don't think I paid near that much, think it was 250-300ish a few years ago. I totally understand. I think you are correct with the 62cc and yes I think you could get good results with your stock heads. But I won't pretend to be some kind of porting pro or anything there are a lot of people around here more knowledgeable than me about that sort of thing.
