Currently my B-GT is set up with a Weber side draft carburetor and an
aftermarket exhaust header system. For several reasons, 1) noise and 2) high
heat from the thin exhaust manifold, I am considering going back to a stock
exhaust system. I have a potential stock manifold (1 broken stud and 2
impacted studs that need extraction). My challenge is making up the
difference in the thickness of the exhaust and intake manifolds since they
are held on by common bolts.
Donor stock exhaust - 9/16"
Weber - 7/16"
Aftermarket exhaust (FYI) - 3/8"
The PO used some shims to makeup the 1/16" manifold differences. Should I
follow suit and use shims to make up the 1/8" manifold difference? Would it
be more advisable to have the exhaust manifold machined? Or is there a 7/16"
stock manifold that may exist in the used parts market?
Thanks
Charles
