If anything; another set of stock rocker arms is a good investment IMO, IIRC not even $150 for a set.

We have sold and installed Hundreds of Harland Sharps without any issues and for those concerned we offer the stocker mod to replace the center trunions and bearings. Stockers are junk without this mod seen way too any fail.

Why hasn't anyone come up with a swap program for the stock upgrade idea? Maybe a $250 fee for upgrade service and $50 core charge until they get your stock rockers in good shape returned to them. If they would agree to that I would get mine done for sure. Had my P/P Throttle Body done this way recently.

Most people sent their stock rockers off the Harland Sharp to get the trunions upgraded so the needle bearings can no longer fail. This costs about $275 and takes some time for turn around.
Well... it turns out that Yella Terra revised their design to remove the "weight over the valve tip" issue. I found them on sale for under $400 so I went for it. They work great and I have no more valvetrain noise than when stock... just some mild sewing machine noise.

I just installed a set of Harland Sharp 1.7's. I swapped my stock valve retainers for Ti retainers (on 918s) at the same time to try and help counter any valve float issues. My redline is 6600 and I don't plan on going any higher than that.
I just got them on, still need to install the rest of my drivetrain before I can't really chime in on results. I do plan on a dyno run also when done so maybe we will see what they are actually worth.
