ProComp/Speedmaster aluminum heads

There are always reviews or experiences that will both support a part or beat it up. You know this. From what I know of those that have bought them (including personal friend), the castings are fine. Some claim better than edelbrock. All suggest buying them bare and have a quality machine shop assemble, checking tolerances. I cannot argue with this, and I believe if you followed that plan you'll have a good experience.
Okay put this idea together for me. On one hand I get the bear heads for $500 or so and then put$800 in machine work? And quite possibly another couple of hundred dollars and valves? And then yesterday I have the guy tells me at Speedmaster $1, 200 for full CNC heads loaded? Now do I take these apart and have them looked at?
Wait a minute I'm broke...
