Anyone know the lengths of the bolts? I need to buy new ones. I'm pretty sure 2 are longer and 4 are shorter? Thanks

Don't those engines use studs to mount the manifolds, not bolts?

Originally, they were bolts on Chevrolet stovebolt engines (sorry, I do not know the lengths).

Studs and bolts could be used.
An unthreaded "pin/stud" was at each end of the head on Chevrolet sixes.
Contemporary GMCs used threaded bolts at the ends.

Mine has a stud on each end, 6 clamps/bolts in between. I'm wanting the bolt length if someone knows.

The short bolts measure 1 5/16 as measured from under the head of the bolt, so 1 1/4 length under the head may work if you can’t find the 1 5/16. The long bolts measure 2 13/16 under the head so 2 3/4 should work. Remember the head has a dowel on each end to locate the assembly.

The two long bolts get the two short clamps, the shorter bolts get the longer clamps.

Thank you so much. I tried with some odds and ends last night but none seemed right. I'll get these and try again.

The cylinder head has a dowel on each end for the exhaust manifold .
