Everything Ive read, says not to use gaskets...just copper rtv should work, Ive always had problems out of wast gate and manifold gaskets burning out on turbo cars..Try the copper rtv, or find some copper gaskets. I havent installed my On3 kit, but a turbo's a turbo..And they all love to burn out gaskets.

I installed all new studs from ford, used the gaskets and copper spray. I have only started the car a few times.
I really hope they hold up. They do not look like much fun to replace on the car, that is for sure.
