NEED HELP!!!! I think hughes engines sent me 1.5 rockers instead of 1.6 ratio...ughhh

I know it all depends on the length of the adjuster, but all the aluminum rockers I have used ...you only end up with about 2 or so threads up top and about 1 1/2 on the underside.

But I think i saw somewhere that the hughes rockers use extra long adjusters....I guess thats how they get the number, just by exaggerating the lift via adjuster.

Consider the rocker/valve tip geometry, is the wear mark in the middle of the valve tip?

Where in so cal are you ?

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.
