      will this work with the e7 heads with no modifications to the threads in the head?

      • The ARP 7/16 in. Rocker Arm Studs are designed for aftermarket heads that use a 7/16" stud mount rocker. These would be incompatible with the OEM heads which use a 5/16" bolt down rocker. The holes would require being drilled and tapped to fit a 7/16" stud, and will require additional modifications.

      1.72 roller rockers Will these work with comp 1.72 roller rockers?

      • I've seen guys use them with no problem, but be sure to check the valve to piston clearance if using an other than stock high lift cam.
