I talked to KB today, 7/1.
He has the casting.
He said they are finishing machining for Greg Knight right now and they will start the 1st and 2nd machining operations on mine after that, hopefully Thursday.
Then he sends it out for gun drilling for hydraulic (lifter bore, pushrod oiling), about Friday. Lastly it comes back for final machining.
I asked him to verify he has the head studs for my order, and the MLS head gaskets. He said he will call me at the end of the week (Thurs or Friday?). He mentioned that the 7/16" studs I ordered have not been a problem getting, but sometimes the 1/2" studs take longer.

When I asked a little more detail about the lifter bore/pushrod oiling mod, he mentioned Wade's block and the Moroso oil restrictors (which I liked).
