Default good rockers for 6000 rpm, 540CI combo??

I am redoing my mess and starting over with as many new parts I can afford, the engines that failed me the guy used Erson rockers on one, and PBM on the other, first of all having 2 different sets on engines drove me nuts so last year I had mixed on both engines so they matched, I know stupid LOL I had no issues and the rockers seem nice and look good..

My question is what is a decent affordable rocker I can trust at 6000 rpm? will these be ok? should I replace these also? my mind says it's a no brainer but my wallet is tight with having to redo everything all over, may have to use some existing parts worse case, but wanted to know good sets guys trust that I can price out...


Yes the chitty pushrods will get replaced with 1pc hardened...

Throw that pile of junk away. You need a good valvetrain, especially on a marine motor. Tune and valvetrain must be solid otherwise you`re back top square 1.
120wall pushrods, good springs and rockers is a must imop.
I got these from Bob.
Custom length pushrods from Trend

I figured that was gonna be answer... Just another setback from the famous hack... I figured these were fine at 54-5500.... Not at 6000.....I gotta make lots of money.....

I'd use a steel arm Tim. The Crowers or the comp cams hi-tech jobs.
