Could you please explain what is wrong with the Jesel stuff?

Just curious, with the rocker arm being one of the most abused parts in an engine, why not go for the strongest one available. I'm sure some will say it's overkill, until they have a bunch of broken pieces banging around inside their engine.

EVERYTHING about these new engines I'm building is about RELIABILITY with Power. Not putting anything in it that saves $20! Leaning towards Comp Cams Ultra Pro Magnums. Personally havnt had any problems with Jesel Shafts, you WILL have to slightly "modify" them to get the geometry dead on though! VERY IMPORTANT! I think if people have "problems" they most likely just took them out of the box and threw them on?!

You are right. Improper setup (geometry, pushrod, spring ect.) part fails and the manufacturer get blamed for faulty parts.

For your setup I would highly recommend the Scorpions. The Comp stuff leaves a lot on the table to still be desired. The engineering of there steel arm puts more weight on the valve and that's a big no no. With that sort of lift and a hydraulic lifter an aluminum arm will give you many trouble free hours. I've ran the Scorpions @.721 lift 50 hours 6,000 or above.

I am using Scorpion Endurance on my new engines, no reason to have the heavier steel on my application, the life is gonna be just as long, if rockers are set up right there is no failures to happen from the actual rocker being aluminum over steel...
