Dart 23 degree heads
Dart has came out with 23 degree aluminum heads with 220, 232, 248 runner sizes, valves as big as 2.100 all with standard intake runner position and standard exhaust pattern.
They also have the same runner size heads with raised intake runners
and spread exhaust. combustion chambers for standard location heads and raised runner range from 62cc to 67cc.
The raised runner, spread exhaust heads have valves as big as 2.125.
Anyway I sent off for there catalog to see if anything new was going on with dart. looks like they have been busy at dart.

I don't think you are hurting for heads. 
they still have your heads they refer to them as PRO and the new heads as RACE. Damn I figured if you were a professional you were allready a racer. they have other changes i'm not bothering to list. relocated spark plug location thicker walls for porting, I guess you can get out your drill make the 248 runner a 260. for that big 472 small block you built.

From: Who says "Nothing is impossible" ? I've been doing nothing for years.
My new AFR 227cc Elimiators have 2.100" intake valves, just waiting for them to mine the aluminum and make them for me 
I guess Dart has realized that the big inch small block with 23 degree heads are getting real popular, smart move on their part
And then they have always had the Little Chief Heads if you want to get serious about building a small block
