Big carb options.

I would say a 1050 also, here are some flow numbers from a friends 452's with 2.14/1.81 valves.

Lift.........Int........Exh.
.100........86.........81
.200.......178.......123
.300.......226.......147
.400.......259.......159
.500.......293.......187
.600.......298.......188
.700.......300.......195
.800.......302.......199

The exh. side was bowl blended only no gasket matching or porting. Your heads should be something like his. The intake side was gasket matched and bowl blended. The port volume was only about 190 cc's.
