Chuck’s engine build thread!

Ok, well, first off, do you think it’s possible that the corner bolts not clamping enough could cause enough lift to make the intake ports not seal?

I do have a wide band but as long as I’ve had the Edelbrock when you’re revving it out of gear, it’s consistently running on the transition slots and it always reads rich. Any way you look at it that clouds the picture.

If I guy were to put some sealant on both sides of the intake ports on the gasket, what would you use? I’m thinking some Permatex Aviation. I do have that stuff in a good quantity. Not that I’d overdo it.

Yes, if it's not an even clamping force front to back and side to side it'll allow gas or antifreeze to migrate in between the mating surfaces and gaskets. Especially if the bolts are bottoming out. It's leaving a wedge, albeit a very thin one, but a wedge shape nonetheless

Can you mock up the intake (sans gaskets) to get an eyeball read on fitment? Then assess an attack plan to seal it up. RTV should be fine for coolant and intake passages from my experience. Gaskets should be doing most the sealing, and of course use silicone on the china walls.
