Default head bolt question??

I'm installing an STI 2.5l on RS heads. I want to know if the tightening sequence and torque specs are the same as the DOHC heads? I believe so but I want to make sure.

Thanks,
Jose

its the same on all DOHC. I would recommend using head studs from ARP. We use them on all the engines we build and have yet to blow a head gasket. The factory bolts are stretch bolts so, if you run alot of boost they will stretch.
