Im running the cups on my 799s. They are the ones that came with my PRC springs. It may depend on what springs you are running, since the top hats were the ones that came off.

Isn't the Machine shop building the heads? Seems like I would let them install them.

I'd run the GM guide seals if you're running the OEM springs (or any beehive spring).
