now that i got a performance head, which studs you guys think or know are better... arp or cosworth? majority count wins unless i find someone who really knows and tells me whats up.. thanks

 

ARP

 

The Cosworth studs have a higher tensile strength rating of 260,000 psi as apposed to ARP for the MINI of 200,000 psi. I don’t know if that matters given the limits of cylinder pressures on our engines. Cosworth stud kits (PR7422) cost on average $70 more than ARP kits (201-4301); both brand’s studs can tolerate re-torque multiple times, so “better” is a relative term in this case including any esoteric value you may attach.

 

Anyone know what the cosworth studs should be torqued to?

 

What ever the OE spec calls for.... special gaskets may require different specs - that requirment is always included.
