Title: Heads up, Harland Sharp rocker shafts
Post by: allrightmike on February 11, 2025, 06:15:42 PM

Was having trouble sliding rocker assys. down over the mounting studs. Upon inspection I discovered stud holes in the shafts are off center as much as .025 and as most of you know that converts to .050 tir. I have corrected this on my shafts but not everyone has a milling machine handy. Now don't get me wrong, I love my HS rockers and am aware HS have a fine product. Just something to be aware of.

I would contact HS and let them know of the problem.

What heads are being used in this instance? Possibly a head issue not a HS issue?

I've ran into cylinder heads that were off a little bit.  I had to grind some T&D shafts once because some factory TP heads were off on the spacing.

I did fit a straight edge along the rocker studs as installed in the head and they appeared to be in good alignment as was the spacing. Also to be clear, there is no doubt that said mounting holes were definitely off center and centering the offending holes cured the problem.
