ah, I wish I had the answers to all your specific questions, but I just gave the shop too much reign.

I hope to god Summit sent the correct head gaskets, as the intake gaskets they sent were wrong type, and failed.

Just picked up the car Friday, and the overheat problem is gone. I still plan to add an oil cooler when I relocate the oil filter, it is almost touching the headers.

I have picked up an old clutch fan assembly, and will look into installing it with a shroud. Although it is cooling ok now, in 70 degree weather, I question if it will cool ok in triple digits when summer is here.
