$350 + shipping. Rebuilt stock iron 8445 cylinder heads including ARP head bolts.
Quoted from my November 2002 Jack Merkel invoice…"Machined with 3 angle valve seats. Exhaust seat bowl area enlarged. Reconditioned intake valves. New exhaust valves. Exhaust valves undercut to enhance airflow. Machined exhaust guides to accept stock type valve seals. Assembled with stock replacement viton seals. HD LT1 spec valve springs.”
Jack charges $450 for this service now without including the cost of the heads to begin with or the cost of valve springs.
These valve springs are for a flat tappet hydraulic cam.
I have ~25k miles on them. Heads were just surfaced milled by Jack Merkel ($120 cost) to clean them up but never installed since they were resurfaced. Although they are “perfectly” flat, I would only recommend stock type composite head gaskets because of the surface roughness.
