Header gasket question...
I installed Hooker headers and used the GM steel gaskets. I have a leak at cylinder 8. I'm going to try to tighten the bolt and see if that corrects the issue. My question is whether the Fel Pro header gaskets are better at sealing than the steel GM gaskets(if tightening the bolt doesn't solve the issue)?

Bit of advice my friend gave me- don't tighten too much. It's easy to overtighten one bolt then it starts warping the header flange a bit and makes it worse (pressure is uneven across the flange). If you are going to tighten, maybe tighten all of them? Perhaps someone with more experience can chime in.

In that instance it may be better to use a stud so you arent pulling threads.
The felpro gaskets are trash honestly. The gm mls are the best for nearly every application. Once they are crushed you cant really reuse them tho. And if tightening it back doesnt work then youll prob need a new gasket with some lock tite on the threads or studs

Ive never had an issue. And ive installed quite a few. I never apply anti seize to anything. Yes ot normally comes on new O2 sensors, but thats all I've ever installed with it on threads. If i am putting a sensor back in, i wont purposely put it on the threads. Ive seen way too many issues with it to recommend to anyone.
