I'm getting close to switching to a roller cam in the big block!

What you have are very good rockers they have the same load rating as HS rockers. I believe HS can handle 900 lbs springs standard or HD the series is rated for 1000lbs. I believe mopars are rated HD. Those mancini's are designed and manufactured by Harlan Sharp and are similiar in design as the old faithful cranes rockers made in the USA. When crane stopped making theirs, mancini stepped up and filled a void in the market. Hughes also has similarly designed rockers for high spring rates.
PRW rockers are made in China and designed here. Someone else would have to chime in on stainless steel rocker fit on a edelbrock rpm heads. Its not a combination we have done.
Aluminum rockers can give up over time if you are pushing them racing w high spring pressure's. But with most solid cams they will last a very long time as they don't see much load. A hydraulic roller isn't stressing much either when you are talking about a rocker rated to handle a 1000 lbs spring.

My HS Mancini rocker shafts had some premature wear. My builder had questioned the very tight clearance and minimal oil galleys when he put them on years ago. I just purchased a set of Stanke Motorsports shafts for them and he absolutely loves them, especially the oil valleys.

Been looking at those shafts, if I didn't already have shafts with banana grooves I'd probably buy those... The ones I have had threaded plugs in the ends, which interfere with the valve cover slightly... The Stanke Motorsports shafts have plugs sealed with O rings... Very good design..

Will the Stanke Motorsports shafts work with Comp Cams Ultra Pro Magnum Rockers?

The Stanke Motorsports shafts are stock diameter, thick walled so they won't distort or deflect... They have lubrication grooves... Unless Comp did something weird which I doubt they should be a great choice..

Did you make a choice on the timing cover? I read most of the thread but never saw you mention my billet cover. The billet cover costs a bunch, but it solves a lot of those issues.

Thank you.
I can't justify $470 for a timing cover and cam button. The features of the precise cam timing adjustability by way of the removeable cover are probably really good for people that need it. I don't think that I would use the special features to make the cost worth it to me.

I include a plate that allows you to measure the backlash. The timing cover gasket makes a big difference so you have to be careful about which gasket you use.

That is a nice piece.

That does look nice and yes, I have looked at aftermarket covers. If one came without a timing tab I'd have to establish TDC and then weld a tab in place.
The cover from Andy has more features than I'd need.

Maybe if you were racing it, andyf’s would be nice to have.

It’s super easy to weld a cam
button reinforcement to the existing timing cover. That’s we did.
