The engine fasteners are non tech. ARP makes a bolt that works perfect on a Briggs animal head and will not stretch as fast as the stock bolts. Call ARP and give them the length , thread pitch and diameter. They are expensive around $15.00 each but will last through multiple head removals.
Chris, Fasteners unless specified ARE tech items including the head bolts. There is no reason to replace our head bolts as we do not take them to close to yield allowing them to be reused again and again while still insuring proper joint integrity.
