Yes the wear mark is within Hughes' acceptable limits. Which is 0.040 from the edge of the stem. I'm pretty close to the center. Correct, the only thing that should matter is the adjuster length and taking up the slack with the adjustible pushrod. Maybe my dial indicator angle is off a couple degrees and not perfectly parrallel with the valve stem. Any number of variables combined could make up for my lift loss. Of course, like Rob says about the Mopar engines. What a headache. I just want the correct pushrod length for max lift possible. Is that too much to ask........pulling what's left of my receeding hairline. LOL.
I'm in Ventura.
