Best way to seal intake and what gasket?

I like to use a wire wheel on a drill to clean off the old gasket material and get the surface nice and clean.


You can lay rags in the intake valley to catch any debris and suck it off with a shop vac and then blow it with compressed air.

Then spray with brake cleaner and wipe dry with a clean rag.

Then I put Gaskacinch on the gaskets for the ports and end gaskets and stick them to the block and heads. Then fill the corners with a bead of RTV. Then Gaskacinch the other side of the gaskets and install the intake. I like to use Fel-pro gaskets.

It's a little tricky to get the intake bolts started sometimes, but I get one bolt to start on each side (sometimes you have to get the end gaskets to compress a little) and then work my way up and down the intake until they all are started, then tighten them from the center outward to torque.
