    Hey guys. Searched a bunch and couldn't get a recent thread with what I'm looking for.

    I recently had a leak from the passenger side header, where it meets the block. I have bbk longtubes and had the gasket changed out with the ones that came with the headers. Fast forward 2 months and the leak is back.

    I've heard great things about the Fel-Pro gaskets but can't seem to find a part number. Any assistance would be great. Or, if everyone has a better gasket they recommend I'm all ears.

    I suggest running the stock style gaskets. Also check your header flanges for trueness, my brand new headers were .020" off per port on them. I ran them over a belt sander and got them to under .005", that with the stock gaskets has provided a leak free install.

    I'll give that a check. I guess I never thought of them being off.

    use oem steel..

    I had cut my driver's side in the middle being 2 gaskets.

    I also had used gasket that came with headers..

    I also recommend the stock gaskets. Used them instead of the ones that came with my kooks headers.
