Because of the high-lift camshaft, either shaft-mounted rockers, which take quite a bit of time and patience to set up correctly on the heads, or valvetrain stabilizers, also called stud girdles, are necessary. We chose the Crane Quick-Lock valvetrain stabilizers. One drawback to these is that they often affect valve lash so you have to set the lash, tighten the girdles, recheck the lash, and reset it if necessary. Another is that they don't fit under short valve covers; however, they do fit under the Chevrolet-script valve covers.
