I've spent some time on it. There's a lot of info. out there while not much.

I've left a question (pending) here http://www.felpro-only.com/break_roo...play.php?fid=3, but I think they're going to say what's written below. Seems to be a standard response. Since they mention it, my water ports do show some pitting, perhaps I'll get some epoxy.


"Our gasket should be installed clean and dry, no sealant on the gasket or around the ports at all. A little bit of sealant should be used in each of the 4 corners where the end seals meet the intake gaskets. It's ok that a little bit of sealant gets on the gaskets in these areas only.

Make sure the intake & head coolant ports do not have any pitting that could affect sealing. If there is pitting, fill in the damaged areas with a high-quality metal epoxy and level the filling with the original/undamaged sealing surface to ensure a smooth, flat sealing surface."



Some info on pitting. I may not touch it, not sure what you guys think, I've added some pictures. I think some use JB weld. https://www.gm-trucks.com/forums/top...pittingintake/
