Without doing a search on the topic, I suppose these are prone to failures?

I would believe most are skeptical with heavy spring load applications but not with street applications. We should use Ed Pink's guarantee policy once it starts you own it. There are no guarantees with any performance parts no matter who the manufacturer is.

so i'm guessing no one has used these and can give an honest review?
I'm asking because an engine i'm buying has them installed by hughes engines

Don't know about the 1.6 rockers but, we ran a set of 1.5s on the wife's 'Cuda. We ran them with a Crane solid roller cam for 4 years with no problems. Never any issues with the shafts or the roller tips.
The only reason we are not running them now is that the heavy spring loads caused the bottom side of the rockers to crack. This is the same thing that happened to the Crane gold rockers we first tried.
The engine by the way is a 440 Source stroker 512" that has been running and raced for 6 years now. I am sure there is a good reason to bash 440 Source stuff but, not all of us are made of money and have to try to save money where we can. If that means that I have to go against the popular ideals and buy from someone that I can afford their parts so be it. I normally don't rave on but I just felt I had to vent.

A solid roller usually is speced for high spring pressure , this is not the place for a solid body unbushed alum. rocker ... or an unbushed iron rocker for that matter. If the Cranes broke I wouldn't have expected a CCJ rocker of the same design to be any better.
That said you must not have had high spring pressures because ccj rockers have failed being run on hyd. flat tappets.

Not sure what is considered to be high spring pressure but the spring loads we run are 223 closed and 576 open.

I'm surprised those rockers lasted that long with those pressures, do you only start it and let it idle for a minute once a year?

We have never installed a set of 440 Source rockers on an engine.

I had these rockers...They sat in a box for three years...I asked around because I didnt wanna be a "gambling man". Two words were mentioned to me "needle bearings" and thats all that was said. I sold them. When you put a lot of money into a motor which I have, you don't wanna shortcut the job, save a few extra paychecks instead and get the right parts. I aimed high, I went for Harlands. I find it hard to believe a Hughes engine has CAT (440Source) rockers.
You get what you pay for...

They do have needle bearings....but I failed to mention Made in the USA is far superior than Made in China

It's not the needles that are the main concern with these time bombs...it is the shafts. Needle bearings regardless of whose rockers they occupy require if not demand a true .8750 55ish+hrc hardened rocker shaft to live.

that may be the case but the offshore rockers weak point had been the shaft the roller tip rotates on , too brittle and breaking.
