    rods only 45 with stock Gm bolts with oil. if rods were rebuilt with using a 8740 .ARP then its 50 with arp moly past only . if you use teflon dope on stock head bolts run then up to 65 only. if no teflon sealer then i run them up to 70 with forma-a-gasket on threads bolt hole are not blind on stock chevy 350. so some sealer must be use on head bolts allways oil under shoulder of bolt. i run the cam bolt s to 25. i used grade 8 bolts with thread red locker
