MRE - Aluminum Roller Rocker Arms

Anyone used these mancini roller rockers or know anything about them? I am looking for some roller rockers to use with the Trick flow 240 heads that wont break me, but that ARE worthy of using and not junk.

I have had those on my 440 for 15 years or so. Probably less than 20k on them. Regularly buzz the engine to 6200 as it's a 4 speed. Hold there adjustment well. But I've heard many people on this forum say no aluminum rockers on a race car.

Have some on my 408. No problems at all. Mine are the 1.6. Been buzzed to 7000 many times. About 7 years now.

Are those bushed or needle bearing?

Neither. Like crane. Aluminum to steel.
