349 CI on the cheap

In your orginal post you where talking about using a stock 360 crank and turning it down, not buying a one new. For another $300 more than what you quoted you can buy a brand new set of aluminum heads and not have a set of old reworked stock heads. Also aluminum heads help the motor run cooler and help control detonation.
No matter what you do to a stock set of heads they will never flow and make as much power as a set of out of the box eddys. Once again if a person is using a 360 the you saving the money of having to buy a crank or turn one down and the bore size is larger so that it doesn't shroud the vavles. Even with the 318 bore the eddys are perfect, I would actualy want 2.05 or 2.08 valves with a bigger bore. Unless you are using a pair of w2s your leaving alot of power on the table. When I build myself another motor I'm putting the Brodix ba heads on it.
