In case anyone is wondering what mods Harland Sharp actually does to the stock rockers, I've attached some pics. They mod the LS1 rockers with a better bearing/shaft setup so there is much less chance of rocker bearing failure.
This is cheaper than going to a full Yella Terra/Harland/Adj. Rocker setup, and doesn't add any weight from being added over the valve (less chance of valve float).
The turnaround time was about 6 weeks, but only because they ran out of parts. Call up Harland to find the typical turnaround time.

Nice. I might need to get mine rebuilt soon.

 

Looks nice, I am still caught between these or a comp roller tip.

 

just ordered some last week

thanks for the pics, been wondering what they look like

 

Wonder if they could make that out of Titanium

 

Why would you want to? The valvetrain doesn't see the weight unless it's unbalanced and where the trunion sits...it won't be unbalanced.

 

And talk about a couple grand for a pair of rockers! haha, j/k

 

sweet, glad it worked out for you
