72 RR 400-440 HP manifolds fit on 68 RR?

[Mebsuta]

Will the HP manifolds from a 71-72 Roadrunner with 400 or 440 work 69 RR with 383? 68 has power steering and 4 spd. I know they will bolt on, but will the flanges be clocked the right way?

The reason I ask is when headers that are on there finally rust through, I may just cut them off and go back to manifolds. Will just bolt them on and have muffler shop fab from there. Don't need exact and correct headpipes. My stuff is way too junky for that. Thanks.

manifolds

they will bolt on but they are different the later manifold has a different turn back on the right side but should not be a problem for muffler shop if they are the hi po manifold i say use them and dont worry about it
