Slide,
Are you sure ARP sent you the correct length head bolts? Sounds like you're running into thread engagement problems in the engine block. Did you chase the threads before installing the heads? What lubricant are you using on the head bolts? Did you check if you had adequate thread depth in all the holes by screwing them in with the heads off? If you removed the heads and the head gaskets were not compressed, you are running out of threads before the bolts can pull the head into proper contact with the block.
