What is the best header gasket to use. Are the copper header gaskets worth a dam or not. I have went through several fel-pro gaskets and the keep getting a dam leak. So if you guys know of any better gaskets to use let me know
If the header is tight and flush, the fel-pros should last quite a while. I use fel-pro and found that they last longer with stage 8 locking header bolts. But I heard the copper gaskets are good, but have no direct experience. Sorry I couldn't be of more help.
