Mondello sells them for $350...I'll sell for $250 shipped. They will be brand new, but I wouldn't advise using them on anything that is reaching the max spring lift.
I've got .574" lift, my valve springs max lift is .575" so I think the open pressure is what broke them. They should be fine on a milder engine...but I make no claims as to where they are made or by whom. They are Mondello rocker arms made by wherever they bought them from. If you're interested let me know. As soon as they arrive I can ship them to you.

Those pivots look too thin,as if they should have been drilled for a smaller 3/8 stud,instead of 7/16.
Harland Sharp was supplying Mondello years ago,but I think they have since cut ties.The 7200 rockers that Mondello sold,were Harland Sharps.I would order direct from Harlans Sharp,also known as Custom Speed,if you give them a local visit.They always have some cool stuff going on there,and they were able to make some custom ratios for me before.

I ordered from HS 2 weeks ago...they had to make the rockers, they were out of stock. They shipped today 
I also got 2 new rocker studs on order to replace the two that were damaged. Should be up and running within a week...track day as soon as she's up.

Ok, the new rockers are in...both the Harland Sharps I paid for and the replacements from Mondello. I'm going to use the Harland Sharps and will sell the Mondello replacements. Here are the pics for a comparison:

I also got a complete set of 3/8" pushrods that they sent me even though they had already sent them a few weeks ago. I even put a note in my return for them NOT to send pushrods...oh well, it's no wonder they are having problems.

Hs s50026a
Sorry to dig up an old thread, but really need some guidance on rocker selection. What do you guys think about the Harlan Sharp S50026A pedestal style rockers for a mild street build? I have some ProComp heads w/Edelbrock valves and plan to build a stroked sbo for my daily driver (not planning to race this car). I have not selected a cam yet but don't think valve lift would be more than .500". I've been told you need to remove the oil baffles in the stock valve covers to clear the polylocks with HS rockers. Would the S50026A rockers fit under the stock covers without modifcations? Thanks!

The studs for the HS rockers won't work on the Procomp heads, wrong size.
Just buy a good 1.6 rocker, BBC studs(1.75 effective length), and the short poly locks from Comp and it'll fit under the stock valve covers.

re
I actually had a different issue but I figured it would add to the conversation seeing this was also with Ford style roller rockers.
When I first bought my 468 it was a low mile build, when It arrived during inspection I noticed one of the valves was worn over to one side what I considered to be excessively for the mileage, then we found the roller pin laying in the corner of the head, after checking them all out there was one broken roller pin and two cracked. They were a PSP brand if memory serves me!
