Default ARP head bolt torque specs

OK, the paper says 75ft-lb but that seems excessive for the tiny bolts by the cathedral ports on the heads.

what are the specs for them, factory was 22ft-lbs on the TTY bolts.

The large bolts are 75 ft lbs. You need to do it in 3 steps. 33/55/75
The paper that comes with the bolts has the specs on it. Factory bolts are stretch bolts and use a different torque procedure. I recommend using ARP Torque Lock lube on the bolts for the best results. The small bolts are 22 ft lbs.
