for all you boys running 2 piece 2 into 1's what do you use to get a good seal where the front header slots in?

Lee I am using Permatex Ultra Black for that joint per R&B instuctions. One reason they recommend this stuff is that it won't influence the O2 sensors.
They say to use the "ultra black 598b" but permatex doesn't use the 598b any more just high temp ultra black. Here's a link for you.
