I don't know about the caps, but I have Harland Sharpe rollers on my '01 Ram. I think Harland Sharpe is amoung the tops when it comes to fitment and quality
They were put on a 273 in place of the factory rockers along with hydraulic lifters LOL the geometry was way off and they we're rolling off the tips I could tell and I think the machine shop use them as a Band-Aid...
