What rockers are everyone using now? Been out of the game for a while and not up on the new stuff. Currently running Harland Sharp rockers, but after the last time I had the covers off they were starting to come apart. Build is nothing crazy, street driving 100% of the time now. Trick flow heads so I’ll need a roller tip. Comp? Texas speed?

OP, going by your signature you have an LS3 based 416 using TFS 215cc LS1 based heads. Those have bronze valve guides instead of powdered metal. This is why Trickflow recommends full roller rockers. If the heads in your signature are what we're looking at rockers for then they would take LS1 straight-up rockers. With those in mind, our customers prefer the Harland Sharp CSP-SLS17 or Comp CCA-19024-16 rockers.

Yes it’s an LS3 block with TFS cathedral 215 heads. I definitely will go with a roller. Harlands have been good but figured I’d try something else. Surely something has improved in the years since I built this motor.

Yea I did have to use 3/8" studs and guide plates. They were pretty cheap regardless. I've actually opened my guideplates up just a bit more to accommodate my 11/32" pushrods

As far as the Comp Cams Ultra Pro Magnum roller rockers, I had planned to get a set of those for an engine I'm currently building. I had Nick over at Brian Tooley Racing spec out my cam, and he told me not to get the Comp Cams for my application. He said they were too heavy, and to only run them if you needed the extra strength due to high lift solid roller cam.
For comparison, Nick recommended a cam for me of ~.615 lift and ~250 duration for a 427 LS-Next with twin 78mm turbos with a goal of 1800hp. Peak hp should be around 7800rpm and I should be going through the traps at 8200rpm. So, higher lift/more spring pressure than that.
I went with Nick's recommendation, and got the stock-style LS3 rockers with BTR V2 upgraded trunions.

I have the Ultra Pro Mags on my car, no complaints at all. The main factors in that decision was the fact that aluminum eventually fatigues and breaks, and I wanted the 1.8:1 ratio for more valve lift.
I really like the pro magnums, so far got a few dislikes on them from people not using them, and a good review from KCS, if KCS says they're good I believe him. Even if he wasn't running them.
I also like the Texas Speed factory style rollers
But I don't run either, I just look up what I want to use on future builds and that's the ones I have been looking at, really like the ws6store ones for PM guides
