I know... not ARP, but ive been reading around alot about the Speedmaster studs with alot of people having success with them, and seeing as this is a stockish engine with relatively mild application, these will do. As long as i DONT greese the washers and keep the tq down to 65-79ftlbs, should hold for a while. if i was going natually aspirated, id consider the ARP bolts instead of studs, but ive aleqdt have these.
