Set screws are fine. Use sealer.

I tapped mine and used Allen head 1/4” plugs. Not sure how a set screw would work? Nothing can protrude over the top of the tower, or the valley cover won’t bolt down. I think Katech sells a rivet kit for the towers, but I have no experience with it.

What is the advantage to blocking them off? The cover from my LS2 has a bunch of O rings already, I would assume to seal and block off? Looking around briefly I like the Lingenfelter rivets.

The O-rings apparently are not always leak-proof.

3/8 x 24 by 3/8" long allen head set crews work perfect. Use the correct tap drill.
I used red Loctite for a sealer.
