I drag race weekly & have great sucess with felpro 1406

& I reuse them on frequent tear downs & I even save the old ones and use on my street rides.

I use them with no coating. I use anti seise on header bolts. They go on nicely as you only need the end bolts to be put on and you hang the gasket on those two starter bolts, insuring correct alignment the first time.

If the headers or manifolds are uneven use a skim coat of this stuff

: Victor Mender and Exhaust System Sealer .

I use this on collector gaskets with zero blow outs. Also for repairs or holes in exhausts coat a screw or bolt with this and it will plug up to a 1/2 inch hole forever. I discovered this stuff over 20 years ago when my Ferrari headers air injector ports rotted out. I was broke so I used as a temporary fix, that was in 1987 & a 100k later still tight & leak free. I think its the same stuff that you use to seal wood stove pipes:-)

Hope it helps
