the 416 castings from the lg4/l69 cars a very populare choice ( i have a set i am just finishing up, going to go on with a wieand single plane intake manifold.
i think that lb9 heads would be nother good choice (sorry i don't have the casting number)
alot of people also have alot of good luck with vortecs, they can be found fairly cheap on e-bay and other places.

Did you get out 17 head bolts per side? 7 long ones and 2 medium ones under the valve cover, and 8 short ones under the exhaust manifold?
If the short ones are still in there, it's going to be tough to pull those heads.

I am interested in that list as well.
Here are snips of "info" I've collected to far:
Hope it helps, I am unsure as to how accurate it is.
These heads are cast iron
They fit on GM 305 1987-1992
They have a "Center Bolt" patten
I am told that they come off TPI-powered LG4 cars.
They may also have been on LB9 and L69 engines (1987 Monte Carlo?).
I see references to flat or roller tappets, mechanical or electric fuel pump and center bolt valve covers.
As I understand it, 416 castings are similar heads with a perimiter bolt pattern (pre-87?)

Yes, your info on 416s is correct.
The casting number is under the valve covers, stamped onto the top of the head. It is the last three numbers from the eight number stamping that identifies the heads. Once you have that number go here to identify it: http://www.mortec.com/
