340 MANIFOLD VS MAGNUM MANIFOLD ?

Yes my car is a 68 barracuda and the engine I will be putting into it is from a 1974 truck.
I was curious about the manifold from the Cherokee mounting tightly to the head. Also strange thing but my heads do not have the small gas port holes below the exhaust ports
68 Barracuda with 74 small block mopar should be no problem!! Now you need a 70's 340 driver's manifold.
