Came across a good deal on a set of Harland-Sharps, so I picked them-up. These be for use on my mostly street 471 stroker.
I'm a little concerned about the long-term reliability of these on the street. Being fully rollerized, I'm assuming they will hold up fine.
My first preference would have been a set of stainless steel Comp Cams Pro-Magnums. A good deal hasn't presented itself, so I nabbed the H-S's.
So, should I be concerned? Should I start looking for someone who wants to trade? Should I run them and forget about it?

I don't have an answer for you, but I had a set of H-S 1.6's on my Chally to start off with. My car is 100% street. I changed them because I thought they made too much valvetrain noise. I went to Comp Cams I think. But anyway, I'd be curious to hear about the longevity also.

I've heard nothing but good things other than the previously mentioned noise. Never heard of anyone running any real high mileage on them either.
Mine isn't a daily driver, but I do drive several thousand miles per year. I want this motor to be bullet proof. I definitely don't want needle bearings circulating in the crank case!

Bomber,
Did the valvetrain noise go away when you switched to the Comp rollers, or does it seem to be a characteristic of all roller rockers?

I have customers who have been running the same Harland Sharp setups for years on the street with no problems. I have a set on our race car but it does not get a lot of miles on it though (1/4 at a time!). If you need anything or have further questions on the Harland Sharp products send me an email and I will try and help you out!
Good Luck

Sounds like I can run them with confidence.
Thanks for all the feedback guys.

DynoDave, yeah the noise lessened but because I went from 1.6's to 1.5's, I felt more comfortable with clearances and I went to a fat full turn on the preload. I had the H-S's at 1/2 per H-S recommendations. So in all fairness I can't say that it was the switch to steel from alum that did it. There is still some noise even after double checking the steel ones, but I'm thinking the alum heads maybe transmit more noise? This is my first alum headed engine, so I have no prior experience to compare with.

I would not even be concerned about running Harland Sharps on the street, they will out last std rockers on the street, just maintain the engine and lash them up regularly, and they will last you forever,
