headers
Believe it or not, I have had excellent long lasting results with that "JunK" peaple say come with the headers. It has been 2 years with those gaskets from headman. I never had a need fpr copper. Mr. Gasket Ultra seals have been the best I have used when I have had the need for replacemnets. Even doubled up.
I know the bolts you speak of. But I can not think of there name.
