yes it is
hows that Steve ?
do you believe me? it seems no body else does LOL that's why I don't answer much tech any more, you get all the big-head-todd-know-it-alls-that-don't-really-have-any-real-world-experience that just shoot you down
sometimes getting a buttload of answers just makes things worse. every body has different opinions and experiences. I would have answered Snakes question, but my headers are ball and cup, no gaskets required
otherwise , soft aluminum gaskets rock in my worthless opinion and they are reusable
