I am getting a 3 or 5 angle valve job on them for a better seal then I will assemble them. I am still working on the best cam grind for the heads along with having a 4400 lb. suv. I will get comp to do a custom grind. I still need to get the L92 truck intake to go with them. Hope all is finished by cool weather time. Next Wed. Greg at Phoenix will be doing a stall & tranny mods. Then I can plan my head/cam install. thanks
