Honestly, if I was in your shoes, this is what I would do:
- Compression check just to make see how healthy the bottom end is, should be about 140-150 psi, more is better.
- If the compression is low, drop a cap full of oil in each cylinder, if the compression jumps, rings might be going bad. If it doesnt go up, then HG might be your issue.
- 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.
