I would use ARP bolts or studs...torque to the ARP spec using the supplied moly for lube.

The ARP spec for bolts is 75 ft/lbs (using moly for lube) when used on an aluminum head. I'm pretty sure ARP knows what they are doing concerning their hardware. ;)

If it were me...I'd replace the stock bolt with ARP and call it a day. I personally would not re-use the stock head bolts...having said that, the Toyota bolts are high quality and you will probably be fine if you do re-use them. Torque them down to 75 ft/lbs in multiple passes (10 ft/lb increments) per the TRSM pattern.

I highly recommend you do a search here on replacing a head gasket...there's more to it than just the bolts used ;)

I just did my NA.

OEM head gasket and ARP head bolts at 85 ft/lbs

DO NOT RE-USE the stock head bolts. Worst case, a new set of OEM head bolts is about $75.
