wanted 906 heads or any 383 parts

Beg to differ. ALL big blocks (except Hemi) had 906 heads from 68-70. A 383 2 barrel had 906 heads. A 440 Six Pack had 906 heads. They were all the same casting. You could also use a 346 or a 452 if you preferred. The 452's would have induction hardened exhaust valve seats, use the same 2.08 and 1.74 valves, have a slightly flatter intake runner, but have more short side radius than a 906.

You still think I'm in to Chevies?

I think, sir, you should buy yourself a Mopar Performance Engines book and start reading.

EDIT:
I forgot you mentioned the intake. There was only one 4V intake for a 383 (for 68-69. there were two for 70. one for a Carter, the other for a Holley carb). So a 330 HP 383 (which wasn't a "magnum") used the exact same intake as a 335 HP "magnum" did.
