it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
I might just use the heads on my 4.8, they should raise the compression, correct? 862s I believe.

just that youll lose CFM with 4.8 heads vs the 317s
no you cant swap valves either

If that valve moves freely then you should be good, right? As long as the spring rate on that #7 matches the specs then it shouldnt be an issue, as far as I can tell, but I don't know anything
btw Ive got 243's on my 4.8, so if youre lookin to upgradebut it might take your cr overboard
Thank you for the offer but I think I'll stick with the 317s. I just got off the phone with Lunati a little while ago, they recommended the Voodoo 60510. I was reading around and saw it isnt even worth the trouble. What are your opinions?

Some late 2000s have the aluminum headed LQ4. The issue with the crank is the reason the iron headed ones are cheap.Originally Posted by Quik
