Well for my build I'm going with my d2teaa truck heads that have been rebuilt about a year ago and redoing with some cj valves 2.09 intake and 1.6 exhaust. Then I'll look into some minor porting with just the roof of the exhaust from what I've gathered for info as for now. Engine building for me is still a learning experience for the high performance mods.

I found these
Set 406 heads
C2SE 6090 C 2E4 date code Came off of a running engine Complete
Good thumb print $700
and these
Set 390 HP 352 heads
COAE 6090 D C1AE 6090 A Both have the same date code 0M16 magged OK
Bare havent been warm since the early 70s rusty but cleans easily with light bead blasting needs going through original seats and guides excellent thumb print
Easiest way to bump compression machined chambers open to offers
I like the sound of a 406
that is as far as i got.. im gunna go do some more research.. indeed i love the challenge.
how much room left between the gasket and port?

Not sure what the best head are for sure bud. I think maybe a c4ae??? something like that, 390 gt head is maybe what you want havimg some bigger ports possibly. The obviuos would be edelbrock aluminums but pricey$$ Kieth Craft makes some ported edelbrocks in a choice of 3 different stages getting pretty wild.
Like i say your best bet may be cobra jet valves and minor gasket match porting but only in key areas or it could make it worse. You'd have to ask the pros on that one. I'm sure if you asked me in a month or two I'd know..

You know, the Edelbrocks are nice flowing heads, save weight, you can increase your advance timing, but man are they expensive.
Take a good set of 14 bolt 390GT heads or 16 bolt CJ heads, do some port matching and a little bowl work, and they will flow just fine for street or mild racing, but they are heavy, you can't advance the timing as much, and you still may end up investing nearly as much as for a set of new Edelbrocks after paying for the machine work, parts and porting. You can save money by doing the porting yourself as long as you have access to the tools, and do some research.
It all depends on what a man is after. Or women. You have to think reasonably about what you want. Be honest with yourself about how you are going to use your engine.
Now, I forgot what the heck I was writing about. Oh well, getting older sucks!!!!!!!

There were no 390 horsepower 352 heads. 360 horsepower was the most they ever pulled from a 352. That was in 1960 only and the heads should have adjustable rockers as the 360 hp had a mechanical cam.

Those C2 406 heads aren't a good choice for a pickup engine, especially with flattops, as they have real small chambers and will cause it to rattle itself to death. The D2 pickup heads are a much better choice, good chamber and the later "high" ports- there's no advantage to the early "long" ports, the lower area is dead air, and all the modern intakes are made for the high port

The 406 heads and the 352 390HP heads are close to the same head
The major difference is the date code and the part number
The 352 390HP heads are a two year only deal
They came on police cars in 1960 and 1961
Both sets have the same chamber and ports
The 352 390HP heads even bare are worth more than the 406 heads complete

The large port early heads are not as good a street head as the '65 and later heads and that is why Ford made the change. All the even larger port high performance heads only work better if you are gonna make big horsepower at around 6000 rpm. This horsepower at those rpm is at the expense of low end torque, which is what gives you street performance and truck power. To regain that lost torque the factory opted for high compression and big CID and your motor does not have the compression or the CID.
