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?
