Ian, I think the torque value is established by the fastener, not what is being torqued. If using ARP studs, go by the ARP reccomended torque, using ARP thread lube. I think its 80# with 30wt, and 63# with ARP lube. Those numbers are for the 190K studs.........
Do the heads/block have the extra holes through the intake runners? What does Dart say about their heads? ............Ray
