Actually, the 305 heads are usually better for the 350 block.

Look for some heads off like a 92 305 camaro, they have the tightest chmbers, which raise compression ratio, which means little bit more power.

Depending on the heads you have right now, the valves might be a little smaller, so putting bigger seats in the castings would fix that. Voila, you have a set of 800 dollar heads (same (specs as one of the edelbrocks), for about 2-300 dollars.

You won't be able to run the cheap gas, without it pinging alot, either, so atleast 90 Octane rating. Higher compression ratio means hotter burning engine.

Yes, but atleast the midgrade. Super is a tad bit overkill, but you will definately be able to tell the difference if you use Super unlead....

The higher octane rating is the 'anti-knock' rating. Meaning it is less likely to detonate (blow up too early), as soon as it enters the cylinder., and you hear the clattering.

The mid grade gas would be your new cheapest way out, at the pump.
