Should I keep these heads?

IMO, you will need a lower static to run any cam under 220°.050.... otherwise you have a tendency to detonate. I would go larger on the cam to run the higher static... because it makes more power overall, and doesnt lose drivability. The XE268, and Lunati 268 grinds are on the hairy edge of not big enough. but I'd rather have more power and performance all accross the range, than go lower to run a very mild cam. Just builder's choice there...lol. As far as hughes, ask 10 guys, and you'll find at least 4 that hate them for various reasons. I think they are ok, but very attitudy and god forbid you have a different idea. They answer questions. The matter is not open for debate...lol
