too mild camshaft

More static compression to start. I'd be looking for at least a full point more but preferably 1.75 more. The cam's not bad with the 1.6s. But with those heads I would have been looking at something like the 308R. No need for a dual pattern cam with them. IMO, at 550 it's a little soft as it sits anyway. I'd expect more from it as it sits now.
