Is there any major difference between the two? I have the Torquer V3 cam so I'm looking for some good performing, reliable roller rockers to loosen that valvetrain up a little with. I noticed there was only about a twenty dollar gap between the two with the Harland Sharps being the cheaper of the two.

 

My harland sharps were hitting my valvecovers so I took them off and put the stockers back on. Now they are on the shelf collecting dust.

 

I run the LS3/L92 factory rockers fortified by Harland Sharp with no issues. One of my techs just installed the Yella Terra LS3/L92 on his GTO (he has L92 heads) and he had some issues with two of the trunions not centered to let his bolt go through to install on the pedstals? He had to use the press to center up the hole. He also had clearance issuses, so he had to install his valve cover spacers. His setup is running just fine. When I used the Harland Sharp rockers on some of my previous LS engines, I too, had to use valve cover spacers.

 

No problems with my YT rockers. Easy bolt on with no mods to the valve covers.

 

Same here... and I even shimmed mine up .100" to get a good wipe pattern

 

YT's here as well. Needed to shim for correct geometry but wipe pattern was darn near perfect. I removed the valve cover baffles and surrounding aluminum to smooth the inside of the valve cover. I also put on the 04 valley cover so the PCV is inside the motor. Not nuts on the HS design, they don't look as strong as the YTs.

 

I guess I lucked out. I didn't need to shim mine as the pattern was perfect without them.

 

My Yella Terras bolted up easily with no issues. Really made the valve train quieter.

 

The harland sharps are a little too heavy on the valves for me. I have had bad valve float issues with them on a few cams..never a problem with the yella terra rockers though or you cant go wrong with harland sharp rebuilt stockers.

 

Harland Sharp smooth rounded top makes it impossible to work with any degree of precision with a dial indicator. There is just no way to find a stable point where to sit the stem indicator tip to measure lifter preload vis a vis pushrod lenght. I have them and wish different. I cannot tell you how the Yella Terra fare in this respect.

 

Thanks for the tips, I think I may try my luck with the Yella Terra rockers and see how they perform. Sounds like a good rocker arm from what's been posted.
