Building a 383 and have to sets of heads laying around 882's and 906's.

Here's what i have so far....
3970010 4 bolt block
Forged 3.75 crank
Cam--.440/.458 lift
210/216 @.050
Pistons--.030 Speed Pro
+6.10cc

What would be a better head for this engine...both heads needs to be rebuilt. I know the 906's have a smaller combustion chamber and flow better...
