how does that happen? lack of oil? I would think they'd make a bunch on noise before they siezed up...

In his case using rockers rated below the spring pressure.
Have you ever dynoed and engine or been present for one ? YOu aren't in the room with the engine , headers are usually open , there is a lot of noise .
just chassis dyno.

Just talked to Comp. They said those rockers should be fine with my spring pressures.(or at least the new design ones.)

I thought this came up before and that 500 was the number ?? Are yours considered the new design ?
Mods to your rocker oiling ???
Are they going to warranty them ?

Are these the Comp Pro Magnums? Seems like a few people were having those rockers bushed due to the steel-against- steel galling..... Never mind, i see you have started another post.

Ok finally got back to the dyno. Same combination execept Harlond Sharp rockers...... 657.5 hp @ 6100 638.6 tq @ 4800 on Sunoco 93!! Video of pull Tried a M1 with 1" spacer on it also.... ran 1 hp under the sd. The sd had a more straight curve to it. the m1 was very choppy. Sorry can't find the sheet right now for the M1 so no exact numbers. All in all made 16 pulls yesterday. Only "scare" was losing 50hp on the first run with the M1. found a piece of bowl gasket in the front jet. No harm no foul!! Very Happy!!!
