Header gasket

[MDmounty]

I wanted to see what would be best for me for my header gasket. I'm going to be safety wiring my header bolts in since they keep coming loose and I want a good gasket on there that will last me.
I've read that I should use a copper one, a copper gasket and rtv, and I've read just use rtv by itself.
I'm leaning towards copper headers but on my passenger side I have very little clearance between one of my tubes and the shock mount which I feel like I should use rtv.
What would you guys suggest I do that would last the longest?

RTV will never stand up to the heat a header produces.

It's just going to burn off.

remflex gaskets. lots of guys are using them with tmh headers. you might have to tighten the bolts maybe once after a few heat cycles then you should check them again every once in a blue moon
