Clearance near the firewall is even tighter for the rearmost fasteners on the driver-side head. Once again employing zip ties, Flynn anchored the rearmost studs in place before lowering the head onto its respective alignment dowel. After the heads were successfully positioned on the block, two M8 head bolts were installed (a little more than hand tight) for added insurance while Flynn began dropping the rest of the ARP head studs into place. Once the studs were threaded (hand-tight) into the block, their corresponding washers and nuts were installed. In order to get a socket on the rearmost bottom stud’s nut, Flynn had to massage the insulation blanket on the firewall in order to clear the ratchet. He told us that on occasion, loosening the motor mounts and lifting up on the engine is enough to gain adequate clearance to tighten this fastener.
