308s vs Magnums

I am planning a fairly mild/econo build of a 360 for my Dart; I talked to a machine shop owner I have known for years and posed the same question about the heads- the magnum is a better head, but the involved adaptation of the magnum head to the '92-down block is more trouble than it is worth in this application. Money-wise (at this performance level or lack thereof in some eyes), I was told to have my 308s' gasket matched, just cleaned up abit, and a good rebuild (multi-angle valve job, heads milled, MP springs w/ dampers, etc; standard fair stuff). Then I'll be on par w/ the magnum head for less money :salut:
