Budget cylinder heads for a 318

The Edelbrock RPM is the best power maker.
The Chinese knock off intakes are cheap as heck and do OK at best.

So there is a edelbrock rpm manifold just for the magnum heads? I was told that the LA intake manifold will not fit the magnum heads due to the angle of the bolts. Are the magnum only intakes more expensive than the la intakes?
