Stock Exhaust Gaskets w/Headers?

My experience is the same as responders 2>4;
stock or cheap gaskets without silicone will not last. I have had some success with hi-temp RTV/silicon yes, but clean up is a pita

I install studs into the end holes of the header flanges of the heads,
then notch my gaskets to fit.
This lets me hang the headers, start the nuts, then drop the high-quality gaskets in last, without sealers..
Easy-peasy.

And yes, I try to use the slanty round, manifold, cup-washers here as well, they just never come loose.
