00 Focus SPI Question

[hacsac05]

I recently bought a 00 Focus SPI very cheap and had been told it got hot and had a blown head gasket. I removed the head and I have concluded the head is warped and may be cracked I have not pulled the valves. I have been eyeing the reman head from headsonly on ebay for 250 dollars. I called the local machine shop and was told it would be around 150 dollars and that is if the head had enough aluminum protruding past the head to roll over to keep the seats in. This does not include new seats, just checking it out milling and the seat "rollover" procedure. My questions are does anyone have experiance with this procedure, the reman? Should I risk the machine shop or just get the reman?
