Usually, you would want to run a fairly good sized head and cam to enable this motor to breathe. In your case, if you are limited to a dual plane intake, you might as well match all the other parts up to that intake and buy a smaller head that still flows well. That will make for a very responsive very torquy motor. It will probably stop making power at a relatively low RPM, but it will make alot of power up to there. Below is what I would recommend and an article with a similar setup.

AFR 195cc (street or comp ported depending on how much you want to spend)
Performer RPM air gap intake
XR294HR cam (242 248 @.050 duration .540 .562 lift +1.6 rockers = .570 ..592 lift)

With the size of the motor, I think you should be able to get away with running power brakes, but I would call comp and see what they say. I recommend going bigger on the cam than in the article because I think it matches the motor better.

Here is a similar motor and what it did
AFR 195cc heads
236 244 @.050 .550 .550 lift solid roller cam
single plane with fuel injection

Made 560 hp @ 6200 RPM 547 ft lbs at 4700 RPM

In the article, they used a single plane and fuel injection, but I think your motor should still be around 530 hp at a lesser RPM pretty easily and more torque down low. I think it will fit under your hood. I had a 1972 ventura (same as a nova) with a small block with the performer RPM that fit, but barely. (I had a 3" or 4", not sure which one, air filter with a drop base) I dont know if your block is stock deck height, or if the Perfomer RPM air gap is taller than the Performer RPM. You can see the motor in my photo album

If you wanted to go with a dual quad setup that might fit under the hood, the one below might work, it is not cheap though.

Also, AFR's new heads have 65cc combustion chambers. With those heads and your pistons with a .045 piston to head clearance, you would be right at 10.2:1 which would be about perfect.
