Comp cams ultra pro adjustable or non adjustable under $500. They now have the ultra pro XD version...they sell what was done...larger stud version
Non beats that ..ftw!
Forgot, custom pushrod guide plates are needed with the larger stud. ....welder up.

Aluminum bodied rocker arms are for hydraulic lite weight stuff. Which one is stronger aluminum or steel. I don't count rocker arm weight. Think about that 1 for a second? Nor pushrods? Y? What are we trying to control... Lose weight there. Springs, retainers, valves,keepers, etc.....

This maybe true Cole.....but seen more aluminum rocker breakage or failures. Most tend to go for steel in the hi hp and keep it simple theme...Jesel is another league in valve train. Crower steel shaft mounted LS7 rocker arms for my other head....or just stud it and repeat like the Ls3 heads..this time no guide plates.
No, most go aluminum.
It acts as a shock absorber for a really nasty solid roller setup. Plus, race parts get replaced more often. Lasting 100k miles is the last thing a race team cares about. Weight. Shock. That matters.

That must be with a ls .....if you go to any other forum most tend to say STEEL for the Avg hi hp build...BBC, SBC, SBF, BBF, Dodge etc. Most hi end exotic builds use aluminum as well as some avg builds. Steel don't move.

When I asked what rockers are recommended, Crower Steel $haft rockers vs the cost of Jesel.
This or I ain't no hi end race team with $ to blow with up keep. 1 guy & the Last thing I'm worrying about is rockers....Springs and interval oil changes is more burden some.

I’ve talked with several builders I know in the business including Dr. Mamo about running the Jesel Mohawks. These guys are nose heavy. They are a lightweight purpose built endurance rocker, but have more nose weight than my YT’s, which would require more valvespring, which is counter productive in making power in a max effort engine, which endurance engines are not. The absolute finest rocker system on the market today, nonetheless.

Old news....basic metal chart. Steel doesn't move as much. Good with heat, wouldn't think of using aluminum with anything where stress is involved. Rods neither... Maintenance is more frequent dealing with aluminum.

BTW.....they're not much lighter than the Comp Ultra Pro-Mags (1.8 ratio) that I've also had, but they are lighter.

I just know that I wouldn't run aluminum.....been there, done (with) that!

You get it.... aluminum can't take stress as well as steel.
KW one thing...the option for being adjustable with comp cams rocker under 500 bucks. Will work with smaller solid rollers. Bigger stud mod for larger lifts.
