I followed their instructions on both motors I have built with no problems what so ever. 3 equal steps up to 80 ft/lbs
Did ARP fix their washer issue?
No its still a pain to put in, i had to prop up the head on 2 plastic boxes to put the washers in and then drop the head fully. But if u have one of those magnets on a stick its not a big problem.

What kind of power did u get from ur engines? And what boost levels?
Well for awhile there ARP was using washers that had a smaller surface area than the OEM washers and I heard horror stories of the washers digging into the aluminum then people having gasket issues. I used factory washers instead of the ones that came with the ARP kit. This was years ago though so maybe they have remedied that situation.
The first motor was north of 600hp to the wheels and the current one did north of 800hp on 35psi. You should be good to go if you torqued to 80.

JZ's I've built have seen 800+whp and never had an issue at 80 ft-lbs w/motor oil lube. Stick with the stock washers if the supplied ARP washers are smaller diameter.

I hope you upgraded the rods at least to non-vvti rods, because boost and stock VVTi GE rods ends poorly.
