Yeahhh, it is weird!
Intake Manifold Ports are about 3/16ths of an inch too low to properly meet the Intake Ports on the Head.
Exhaust Manifold ends of course, register with an alignment 'Peg' on each end, the Pegs being in the Head.
Exhaust Manifold ports appear to meet the exhaust ports in the head, just fine, no alignment problems with them.
It is as if the Intake Manifold had shrunk...
The way the two Manifolds bolt together, there is no provision for any adjustment of course.
I will post their Casting Numbers here shortly.
It was difficult getting them apart, too! Man, they had really been stuck together a long time.
