- I would then re torque the ARP head studs and then check the compression again. If the compression doesnt get better, then I'll start tearing down the head.

I'd get the head decked, stock Nissan HG, cooper spray the HG just for good measure and torque down with the ARP studs.

Everything was good advice besides the copper spray. Do not use it, it doesn't need it.
