Sure, we found a broken rocker on the exhaust side of cylinder #1. As for the cylinder head rebuild, the cylinder head gets pressure checked, then all 3 surfaces get machined, all the valve guides get replaced, new intake and new exhaust valves are installed with springs and retainers. We bolt that back down with ARP head studs and a fresh head gasket.
Thanks for the reply. I heard it run before it came to you. I thought it was in the valve train but wasn't sure what. Good to know .
