For sale are a set of ARP L19 head studs, nuts, and washers for 6 bolt 4g63. Ran for maybe 2 months at most, and torqued down once. These are in great shape and being stored in oil, and ALWAYS ALWAYS ALWAYS handled with nitrile gloves. Price is $185.00 plus shipping and PayPal fees. I will include what's left of the ARP moly assembly lube.
