Which aluminum heads?

So the guy churning out hand ported heads is just blindly porting and each head is vastly different? Did not know, thanks for that insight. Here I was thinking they too developed a good port geometry and used foam inserts to replicate it time and time again. Mai bad.
This was done back in 2008 by someone other than the popular bashers the LE crowd were so butt hurt over after some intake ports of LE heads were posted and looked pretty similar to the ports on the right. Then there's the threads on pin holes and valve springs and cracked valve guides and top ends destroying lifters, etc...
Don't shoot the messenger!

Ever see this?

So I think I have narrowed it down between the LE trickflows 21 degree heads which would 2100 or the afr 210s for 1800. I got a quote on the afrs from a company. Only difference is I will need to do some port matching with the afrs bc they are lt4 designs and 23 degree heads. What's the thought between these two.

I would be running NSA rockers on any H/C setup regardless.
There are a few weird things about the 210s you should know. There is not enough meat on the top of the LT1 intake manifold to safely seal the intake ports so the LT4 is a necessity. The springs that come on the heads are for a solid roller cam so you'll have to swap them out if this is a street HR setup. Finding valvetrain parts can be difficult because of big installed height and beadlock valves. Also, you might need offset rockers (I certainly did) for adequate pushrod/head clearance.
