Alright-you see I knew I would get a decent answer! Ok now how would you build it? Im will be installing 2.14/1.88 valves and a bowl blend would be in good order too! And the rest of the engine...
How stout of a motor are you looking for? What car you dumping it in?
Mine is 915's and runs well. Idles well. Would do well in a street car(I street drive mine)
Home ported 915's with STOCK valve size. fairly mild, but massaged. 440 .030 over with 6 pack slugs 10.6:1 comp 242 @ 50 hydrualic racer brown cam 1.6/1.5 combo roller rockers eddy rpm manifold 750 mighty demon 3400 stall 9" converter 373 gears. junkyard headers 3" exhaust back to the flowmasters, and 2.5" tail pipes after that mopar electronic distributor, with aftermarket fbo ign box Holley blue pump with 1/2" supply line to dual feed -6 lines from the reg to the carb.
As it sits now, my best pass is in the sig line. The car was a little lighter a few years back(added a dana and a second battery) so it was as fast as 11.70 then(still the same motor, converter, etc). Still over 3800 pounds even then.
FWIW, I ran the same motor with a set of 452's that I ported(in the same way the 915's are), and stock rockers, and it was 7 tenths slower.
My mild 440 is very close to Dave's build here but I run a .557 solid cam and I use 906 heads with KB quench pad pistons. These pistons have a flat pad that goes up into the combustion chamber. Not for a raise in comp but to get the piston closer to the head for quench. I run 10.0 comp and I did some port work on my 906's. I also run 4.30's with 30" tires and I drive it everywhere including to the track. My best is 11.52 in my 3700 lb 63 Sport Fury. But if I had the closed chamber 915's I would use them over 906's as they work better using a flattop piston at zero deck to get great quench. Definetly use the 915's. Ron

To add to that I ran a stock .150 holed 440 with 906's and a .528 in a 3650lb 64 Pol to a 12 flat. Mind you it had a5500 stall. The thread is in archives under smogger 440s.

choosing between the heads you have, 915's, no brainer.
if you wanted to do an ultimate iron head BB, I'd say iron indy S/R's

This is a been there done that post. I had a set of 516's that I had originally for a 383 build. I spent probably 30 novice hours grinding on 'em, then had them rebuit buy a reputable speed shop here. I then increased the valve sizes to 2.14/1.81 and the shop messaged them to get a 250 cfm flow number on the intake. They installed dual springs for the cam I was using. They worked very well and would pull well thru 6500 rpm. Your 915's would probably do a little better than the 516's with the same amount of work. Here's the rub. I purchased a set of CNC'd Eddy alum. Heads for about the same amount of money that I had in my 516's. These flow fully 70cfm (as actually measured) more than the maxed out 516's. So that is why you are getting the alu. head debate added in here. So if your going to use the 915's I say go for it. Just know that to get the full potential out of them it will cost you some coin.
