Hemi valley head bolt tool

[Fran Blacker]

Torque adapter. MAC has them individually. They are 3/8" drive though. Crowfoot and Torque Adapter Wrenches

Mine Mac survived the torque. Reading posts, guys said they only torque valley studs to 40/50 ftlbs.

Fast forward, got the adapters . Did not torque up to the factory specs for the valley studs. Concensus is that torque setting can or possibly does warp the intake valve seat area. So I torqued them at about 45 ft lbs.
Thanks to everyone for the help!
