Yeh, Your right. There is plenty of good heads on the market these days. And as the dollar has been so good for the past couple of years the prices are cheap as. Although the Aussie dollar is falling a bit now the prices will start going up.
It depends what your building, and how tough you want it to be. There are plenty of good heads for sale S/H. Brodix, AFR, RHS are all pretty good heads. I don't use ProComp heads/parts.
If you get Brodix, some have both stud patterns on the exhaust ports, but most have the stahl bolt pattern to allow 2"+ primary pipes. While this is great on a race engine remeber that you can't buy off the shelf pipes with this flange pattern, and will have to get a set made.
In saying that, we used a set of ported -10 Brodixs on the engine I built for my brother(in the pic) These came off a sprint car in the US, and got them for $1100 with roller rockers as well. Had to get custom pipes made. I gave Fat Pipes in Brisbane all the pipe sizes/lengths I wanted them made to and they did a great job on them. Overall, for the result we got it still ended up pretty cost effective.
I'm using a set of 220cc AFR's on the 400 I'm building for my ute.

Also you need to think about what sort of driving your going to be doing, and what you expect out of your engine. How streetable you want it? fuel economy? all out HP? Send me a PM if you want
