No problems here.. How are you torquing the bolts down? You are supposed to be doing each set of rockers with the piston at top dead center and using loc-tite and 22lbs.

Everyone is scared of running things when its the installers fault that the parts fail and everyone gets all freaked out. For example Comp 918's, HS RR.. Etc.. If everyone installs them correctly you will not have issues. There are SERVERAL people running them without any issues and me being one of them.....

. Actually Harland Sharp hasn't been a real good brand even back in the early 90's. I bet a lot of people bought them because they were a pretty bright orange.

Harland Sharps for a few years, same set on their fourth set of heads; no problems.
Nothing is perfect, I would use either Harland Sharps or Yellow Terra (or of course Jesel etc.); yet I have only seen the YT UL failures in person.
EDIT: Actually most failures I have seen were installation error, with the extremely rare material failure.

So this must be the other half when you don't know what you are talking about.

Most Harland Sharps don't like high RPMS, but I guess you would know something like this? Apparently not...

Still, I am considering the upgrade to the Jesel rockers anyway; just saying in the years and tons of miles we have had on the Harland Sharps not a single problem with them.

We were actually thinking about doing a trunion upgrade to some stock rockers, the only thing that has me hesitant is that we are running TFS heads. There is no way I would run anything less than the Jesels to near 8k rpms...

I've seen people have no problems at all with Harland Sharps but around this area they haven't had that good of a reputation of lasting and I know they weren't installer faults. Just kinda ticked me off a little when the above guy pretty much told me they were installed wrong, or I just took him the wrong way.
But yeah, Jesel is definitely in my future build as well

I plan on doing a new stroker build pretty soon and it will be 421CI or bigger. Just trying to get away from having to use nitrous to run in the single digits. It won't be a "budget" build like the one I'm currently running.
