Should not make a difference...
However if you are taking heads on and off studs are reccomended so you don't have to clean the bolt holes everytime

Who ever asked about tqing procedure.... ARP does not provide a tqing procedure....
However follow these rules with arp bolts:
With Arp Lube
Torque all 15mm bolts to 30lbft in the torque sequence above. Do a second pass at 50lbft, and finally a 3rd at 70lbft.
Finally install the 5 smaller ARP bolts and torque them to 22lbft.
With motor oil:
Torque all 15mm bolts to 35lbft in the torque sequence above. Do a second pass at 60lbft, and finally a 3rd at 85lbft.
Finally install the 5 smaller ARP bolts and torque them to 28lbft.
