I was told not more than .010" with 2.02" valves and 232*@ .598" lift 0* advance.

That's what I'm running with a Futral F14 and 5.3s..well soon. They should be done in about 3 weeks.

Yeah, when I talked to Futral they said with the F14 to stay with 2.02" I'm going with the F14-112-0 (232/234 .598./598) I was going to go with 2.05" intakes, but Futral and TEA adviced against it unless I wanted to get less cam, flycut the pistons or settle for less CR.
