The port openings are CNC'd exactly to the stock LT1 gasket, the exhaust ports and bolt holes exactly match the Fel Pro LT header gasket. The pushrods don't clear the stock GM head gasket pushrod holes, so run an aftermarket one.
They are a true bolt on 54cc LT head, right out of the box they make almost as much power as our LT200 heads.

I'm just trying to decide the better value here. The AI 200cc heads flow very close to the TFS fast as cast head. I can get a brand new set of the trick flow heads shipped to my door for $1400 where as I would have to pay $1700 plus shipping. And I would still have a used casting with AI.

What would be a good cam to run with them out of the box?

Good to hear nothing was revised. I assumed that was the case, but didn't want to speak for you guys. 
You are attempting to compare incomparable data. On the same test fixturing, bench, conditions, etc. our 200cc CNC'd GM head is 25-30cfm up on the as-cast TFS head.
The 200cc GM head is completely re-machined to as-new condition. Our $1395 190cc CNC'd GM head will be a few #'s up on the as-cast TFS head & the 200cc CNC'd GM head will be up a little more than that. At the same time, the first fully CNC'd head based on the 21deg TFS casting we release should be up ~10-20hp over our 200cc GM casting.
Waiting on a few bits of info from TFS before we can wrap things up. Hopefully that'll happen this week & we can finally get this pile of castings cut up & on some cars.

I think these will be the perfect heads to compliment my little hotcam. And I will have room to grow if I want to make more power with a cam swap. I kinda like the hotcam
