The main thing about coating the block or heads is to coat before honing, boring, line boring, etc. as the 400 degree temps. can affect the machined surfaces accuracy. If GM did it, I would think most shops could as well.

I'm surprised, because the guy at Allied wasn't crazy about heat type
applications like BBQ pits and such..Of course a BBQ pit would get hotter
than an engine block. I need to ask. I eventually want to put a 502 in my
car....I need to ask him specifically about a car block! They did a
wonderful job on my 12 bolt!!

In 1991 when the Gen V bigblocks were introduced, Chevy powder coated the
blocks and heads black from the factory. The coating was done before any
machining was done. The ones I have seen have held up very well.
