ARP Head Bolts
Product: ARP Head Bolts
Place Purchased: Suprasport (~4 years ago)
Price Paid: $115 USD
Application: 87-92 Supra both N/A and Turbo.
Highlights:Mucher higher yield strenght (120,000 psi)
Rating (1-10, 10 being best): 9.5
Installation Difficulty (1-10, 10 being difficult): 8 (done at the same time as MHG install)
Installation Tips: Used the ARP moly lube and torqued to 85 ft-lbs. The crankshaft had to be turned on occasion to rotate the camshafts so the lobes would move past certain holes...
Additional Comments: The head bolts have a 12-point head. I originally freaked out thinking I would need some sort of reverse TORX socket, but the bolts fit a 12-point socket perfectly.
