Unless you're buying china heads it seems you can always beat a new set of heads buy having factory castings CNC ported and fully gone through. Maybe not by much but still cheaper none the less. I just went through this myself with a set of 243s. I wound up with about 1500 into them including the price of the heads up front and shipping. A good fast as cast head with good springs will be more than that.
I also am very interested to hear what heads you went with and why you didn't just come right out and say it? I'm not saying that as some kind of douche call out nonsense, I just like to know for myself when I've really thrown good money away lol.

I went with Texas Speed. By no means am I saying they're the best. I've been working with them for around 10 years now and they've always treated me well.
I also went with the 2.02 valve conversion. Again probably not needed and it did add a couple hundred dollars.
Car will be hitting the dyno for a very quality tune in about 10 days. We'll really see if it was worth it then.

Those are fantastic heads. I was torn between those and the PRC fast AS cast heads. Ultimately I cheaped out a little bit but have been having a blast all the way.

BARE heads means the finished casting only. No valves or anything.

Bare heads are just that. Just the castings. No valves, valve springs, retainers, locks, rockers assemblies, or anything else.

As far as assembling heads, it's pretty easy to do yourself.

For sure do the front as it's the only way to bleed all the sir out. The rears help with that, but not everyone does it, as GM didn't even use them on later engines. I think using the rear steam lines improves the cooling system by ensuring all air is bled out.

The 5-angle valve job can be done by a machine shop with all the valves "assigned" to their cylinder, and OP can still assemble the head.

Thread resurrection: OP, can you share what you did to get the rear head off and out in a pick n pull yard? Will it lift right off or did you have to remove the engine from under the hood? I have my eyes on a set currently and I'm just seeing a lot of cuss words trying to remove that rear head with the engine in place and the car up on stands in a PYP yard. Thank you in advance.
