Since nobody listened to you wanting to keep the stock big stuff:

-The block should be a roller cam block with a flat tappet inside. Buy oem vortec cam, roller lifters, and hold down tray and use that instead.

-You are already buying pistons, so get ones with a skirt coating and a bit more compression. I'd go with 9:1 if you want to use 87 octane still. Get whatever head gasket that will get you close to .040 quench.

Otherwise, pretty much everything on that old TBI system will require a new chip being burned to tune and you don't sound like you want that.
