I guess you have to have the feel for it I use them all day on aluminum heads. But i am also doing it with the head on the bench in front of me. Makes it a little easier

I barely have enough room to get down there and once there my face is so close to the heads I couldn't focus. I had to go to the store for 3.0 readers. Still tough. I worked on them on and off for 3 days to get them clean. I will NOT be using their exhaust gaskets again. Gonna try one of Smittys recommendations.

Dont they make an multi layer reusable gasket like the have for headers ?

You just buy premium felpros or mr gasket ultraseal header gaskets. I coat them with antiseize, reused same set thru multiple rebuilds on my baja. As long as there not ran leaking, they last quite a while, I had stainless marine gen 3 manifolds, Smitty

the whole problem is I HATE anti-seize. seems if I walk with in 5 feet of it I have it all over my hands, shirt, tools, shop floor, bench, etc. I swear you could cover an entire house with a pint bottle of it. other than that it works great.

You ?

I would say yes. Although they might have a teflon (silver/gray color) coating on them?

Mine would be used with CMI headers instead of manifolds if that makes a difference?

Thank you

Worse than silicone!!!

it makes no difference, as long as the surface is clean and fkat, you put a very thin coat on, i put it on tbe stainless exhauat bolts too so they dint gall, especially in aluminum heads.
