SE rocker plates or stock

At what point, lift and or spring pressure are SE rocker plates required or are they at all. The stockers seem to be a little bit harder material to me and less prone to wear. I have a set of SE that show definite signs of wear. Clearance is also at near max on both exhaust rockers.
Thanks

I ran the stock support plate and rockers on an all bore 107" motor with .600" lift cams (124TQ/110HP) with no issues and am currently running the stock support plate and rockers on a 98" motor (115TQ/115HP) with no issues.

I also run stock rocker supports and rockers with .600 lift cams on another bike. With this motor I'm looking at .650 or .660 lift. Heads are set up accordingly. Yes, the SE look beefier. But the aluminum alloy appears to be different and softer. Just wondering if anyone uses stock at higher lift. Last set of SE supports I purchased had sloppy rocker endplay clearance right out of the box. Almost at service limits. Sloppy enough to make me try some shims. But I didn't like that idea and took them out. Last set of stockers I purchased were right on the money and still are.

If you are going to upgrade the support plate, spend the money for the Woods or Vulcan plate; aluminum billet and bullet proof but not cheap.

Yes, the Vulcan is expensive. Don't know what the Woods plate costs but it sure looks expensive. Don't need either of those. Probably just go with SE.

Just found these on the interweb. If I were ever to decide go high end. Looks to be the right kind of billet too.

We work with .650" lift cams here on almost a daily basis.
The OEM rocker support plate is just fine.
I use them in my T-Man 662-2 equipped, 131".

The Wood setup (I believe is $420) is also offset .030", this is from the Wood website:

"Moves pushrod out .030 away and towards center of the pushrod tube. As we all know a problem exists when the pushrod is at it’s lowest and highest points, especially with high lift cams. Thanks to a good idea from Gary Williams & Company, these rocker arm supports move the pushrods away, thus eliminating the normal rubbing contact points between the pushrod tube and the pushrod. When using roller rocker arms with 7 millimeter stem valves, the problem gets worse as the roller rocker tip tries to roll off the forward edge of the tip of the valve stem. This additional .030 inward motion helps to eliminate this problem also."

I will be using them with my .678" lift cams, cant hurt to be on the safe side.
