What brand are the long bolts? Hardin or Harmon? I've never seen a set, I was told that
the ports match up correctly though.
Are there any other brands that work better than what I have now?
I'd really like to use my old upward manifolds but can't because of the tall valve covers. They had a great tone and don't seem restrictive either.
Please let me know what else I could look for as far as a log type.
PS, could someone post a picture of the long bolt type?
Thank you,
