mach 1, my friend and i did an aluminum head swap on his car and reused the same head bolts after we finished he drove it to normal operating temp and went back and retorqued the head bolts there was a slight movement in his bolts. next i performed an aluminum head swap on my car but i used arp head bolts. when i went back to retorque the bolts there was absolutely no movement. He never had problems with his and i never had any with mine since the head swap but i think the fact that there was no movement is just enough cause to replace them, it definately couldn't hurt.

Interesting, and the kind of information I was looking for, thanks...
