The replacement head is back from the shop. I'm very pleased with the work that was done.
After a thorough cleaning and inspection, they found that the valves, guides and seats on the exhaust side all needed some work, which sort of led to me letting things snowball a bit. They installed bronze liners in all of the exhaust valve guides, recut all of the valves and seats for a "performance" valve job, did a bit of porting work to clean up the bowls around the recut seats, bled down the cam followers from my old head (the set in this new head had a fair amount of corrosion), and then resurfaced the deck.
Next, I'm going to chase all of the threads and preventatively install keysert threaded inserts for the exhaust manifold studs.
It'll still be at least a week until this is all back together, but I'll be carefully putting things back together piece by piece. I'm going to be trying out Cerakote air-cure ceramic coating on the outside of the exhaust manifold and turbine housing.
