tightened down all of the bolts on my passenger side header and it still has a huge leak so time to replace the gasket what is a good gasket that is still relatively cheap something around $50 got pacesetter longtubes

 

go with a set of mr gasket ultra seals, did the trick for me and runs perfect now

 

I got felpros

 

percy's soft aluminum header gaskets. They are $30 something dollars and have a lifetime warranty. I've heard from several people they are the best and never blow out. You can get em at autozone, summit or jegs.

You want the d port ones for the lt1

 

Is it better if you use the High-Temp Copper sealant with them?
