    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

    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?

    The eyebrow is not bad, but I would definitely look at removing the valves and have them checked. Something SOMEWHERE caused the eyebrow to happen, which is why replacing the cam, lifters, pushrods, springs and cam is recommended.
    Speaking of the cam, I would like to see something bigger go in there. (HAHAHHAHAHA--thats what she said ) A 6.0 can handle some decent duration and lift... maybe a high 22x/22x duration and .58x/.59x lift on a 112 LSA?

    I had both my heads check out and cleaned up at my local machine shop, Rob said all the valves are straight and the heads are good to go. I dont know why it happened but everything is getting replaced so I should be alright. I still havnt found a good cam though, its the one thing holding me up. Everyone I call recommends something to small. How does this sound? 230/226 .600/.600 113 LSA Its a custom grind.
