Not RPM heads but Harland Sharps in our 360 SuperStock engine program..no corners cut!

Thanks TEd.

Be aware, standard h
Harland Sharps WILL work on the RPM heads, but the fitment is not as exact as I would like to see. I offer sets made to better align the roller tips for RPM heads. Let me know if I can help.




I heard that recently aswell. And you can get harland sharps that work specifically for the rpm heads

The HS are a little long on the RPMs, the rocker tip will run outside of center on the valve tip. IMO, it is no big deal.

I'm using the Comps on my roller cam street car with no problems. I think any of those choices are fine if the new Cranes are the same quality as the old Crane Golds.

Does this hold true for the 440 source heads?

Sorry for thread hijack btw.

They will work fine on the stealth head. I had them on mine.

I call those Shanghai Sharps!

And, no, I wouldn't use them on anything I'd own.

Note the elongated axle holes on this less than a month old set!

as well as the failing upper bridge portion of the rocker body and axle....not good, very poor copies.

The Hughes stuff does seemed priced well and a good value. I think the H/S could hold up a bit better under a little higher loads,and I have some long term experince with them in many brakcet and Super Gas type cars, but not sure what your future plans are, so thats got to be your call there.

The last few set of Cranes I ordered were still the " old" style, and they had not yet started shipping their new pieces, so until that happens, I cant say how godd they actually will be.Roller cams in my opinion need a little better rocker for long term service. Small roller snad solids, the Cranes did work great on.

Todd - Good info!!! IMO, people need to see & understand how these low-budget copies are INFERIOR to the originals in some significant areas. Rocker arms are really not a place where you can "cheap out" with a true performance engine.

I like the Hughes roller rockers I use on my 493 with the EZ heads. They have been working fine and holding up good. Ron





I ran them w/ my Stage VIs and a solid flat-tappet cam w/ good results. I'm hoping they're up to running with 200#s more open spring load w/ the new roller cam.
