Exhaust Manifold Bolts , Big Block

[nuch_ss396]

[ QUOTE ]
I agree with what Rick (mr70) said. My car is unrestored (69 SS Chevelle) and when I removed the exhaust manifolds, the non-shouldered bolts were on the inboard ports and the shouldered on the outboard ports. I tried to put the shouldered ones in the inboards and they would not seat. The holes are not deep enough, at least on the heads on my car. The repops that are available today don't match what came on my car.

Hope this helps.

Phil,

Ok - there are eight bolts per side. If you numbered them
from one to eight ( L to R ), which bolts were of the shouldered type.
