I need 16 for both heads but I only bought 8. It's a Fel-Pro fiber gasket that gets installed dry but there was a little adhesive, from the factory, on there. I guess my worry is that the adhesive activates under pressure and the weight of the untightened heads will spoil it? I'd really rather not go back out to the parts store tonight.
Also, I may have to take one off or at least lift it up a little to squirt some silicone into a gasket that looked like it had a piece missing out of it. Is there any danger there where I might have to unmate the head and gasket for a few minutes after the untightened head has been sitting on the gasket overnight?
Finally, just one last final check... you do install a Fel-Pro head gasket completely dry, right?
