ProComp/Speedmaster aluminum heads

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...
Yes, you'd want them disassembled and looked at. Some of the seats won't hold alcohol if you pour it in the port. You want them taken apart and everything checked.
