What manifolds do you have? These rarely if ever leak.
Got any pictures? You may have to have these badboys milled.

Hardin marine if I recall right. I torque them in a criss-cross pattern and tighten the **** out of them.
I machined the riser's surface on a piece of granite with sandpaper duct taped to it. (my cnc table) and I filed the manifolds surface with a file, took forever and a day. With towels shoved in exhaust to keep particles out.
Original owner had silicone gushing out between all surfaces and it was leakin when I bought it. I did my work to it and used aviation gasket sealer on all surfaces. Well, the sealer just bubbled and melted out once it got hot, I re-torqued on the water last Saturday and saw all the water spots all around manifolds when I got home.

Gaskets should be sprayed with spray tack only.....I use silver paint from Rustoleum.
You should not use any sealer with body to it... ;)

Bringin' out the old school ;)

also the gasket shouldnt be burning... why is that area getting so hot? i can touch my entire exhaust with bare hands and its "barely warm" now.
Gaskets aren't burning, the aviation sealant got warm and softened up. I can put my hands on the riser while its running.

Lead gaskets? Sure, why not.
