rac43,
According to Chevy High Performance the Dart Iron Eagle SS 165 heads flow worse than the 882's but the combustion chamber size will probably work with your combo.

Vortec heads flow the best of the bunch but with the small combustion chambers the compression ratio would be way to high.

The 441 castings are great for making torque but they are strangling the top end potential of the 383 in Mustansaly's example.

The Dart Iron Eagle 180's would work best. The intake flow is about the same as the 882's but the exhaust is a lot better which would really help with your single pattern cam. I'm guessing the 72cc chambers would put your compression ratio around 9.0:1. If you know your current ratio I can tell you for sure. And at least the Iron Eagle 180's would fit your budget.
