Yes that is correct, Budget would be nice. Im thinking a slight overbore, with some stock heads with some at home port and and smoothing of the castings should help it out, I may just make a cleaner engine and keep my Whiplash cam since it is fun to drive I just regret not cleaning up the heads and one cylinder had a slight scar that I wish I would of overbored. Just wanted to see if there was a piston change to boost comp a tad but it seems like more more work and money than the gain is worth.
