69 Exhaust Manifold Bottom Studs

[Craig C.]

I need to get 2 sets of studs for the bottoms of my '69 big block exhaust manifolds. What is the overall length of the stock BB manifold studs? Are they the same length on both sides even though the right side includes the heat riser?

Thanks in advance,

Craig

No, they are NOT the same length on either side. The left side is 2-9/16"; the right side (heat riser) is 3-1/16". Currently, the left side is GM #14088827 and the right side is GM #14088828. However, I HIGHLY recommend the use of stainless steel studs.

Exhaust Manifold Bottom Studs; Correct for '66 also

Joe,

Are those same GM parts numbers correct for the studs for '66 SB exhaust manifolds?

Yes, the same. These are not ORIGINAL part numbers, though. They are at least a "3rd generation" supercession. How they differ from the originals, I do not know.
