The heads are dropped off at the shop and they confirmed that the intake valves are screwed. I'm looking into getting some Ferreah valves, I'm just not 100% sure which ones I can get the best bang for my application. I'll defer to the machine shop on that one. The engine/trans will be going in as soon as the ARP head studs and valves get sorted.
In other news... I've decided to ditch the air to air setup and switch it up. Air to Water is the new direction. Specifically twin air to water and twin BMW 7 series pumps.
My 4l80e is back from Capizzi Automotive. Mine is the non billet TQ converter, that's a future upgrade so I can spin up to 9krpm.
