He also knows how to coordinate all the other players to play well with them. THAT is the difference.
I guess no one else is capable of that? Having to fix or upgrade other parts to account for a part with an inherent weakness (weight) doesn't make a whole lot of sense.

It would amaze you how many don't. Many will throw together a bunch of parts that SHOULD work together, but put little thought into HOW WELL they do so. Mamo puts the thought into the job.
Like I said, I didn't particularly want the YT rockers but at the time I couldn't find anything else. I prefer the TSP roller tip rockers but they didn't have any at the time due to covid-19. My dyno shows no strange dips or jagged lines to indicate any valve train problems. I think the motor just doesn't get enough air with this intakes. The CID/4500 will go on this winter.
I had 2 different individuals same heads and rockers, both peaking early and breaking up past 6600. I had both remove those YT and replaced them with OEM LS7s with a trunnion and corrected their issue. Just sharing what I ran into. I'm not a fan of a heavier rocker. Many will disagree but on a build that you are not spinning to the moon an OEM will do great at 7500+. Shop manager here stock OEM rockers with a trunnion we spin that sucker to 7700.
Here's the Killer with all the money going into the Engine I ask Y in the World would one use some BS?
👇
Jesel / T&D / Crower 👈... anything else for a High performance engine is of Lesser Value or Not made for High End high Hp with Realiablity...
I know about old YT failures and reason I'd never recommend them vs... 👆
Use what Winners use and there Asking for More on Durability with Crazy rpm and lift used Vs the topic... Common Sense 👍

Why you ask??? Nothing was available at the time.....I ran the TSP rockers on my previous LS3 based stroker and shifted at 8k every pass with no problems. Had the LS7 version been available I would have bought them for this motor.

that post was 4 my buddy JR... But once you start getting Crazy with Rpm and lift. Leave no Doubts.
My 🐂 💩 has bushed lifters and Bigger BBC sized studs.. leave no Doubts on Movement even with the use of a 🐂💩 Stud mount. 😏
My 8mm yt never had valve control issues ls3 heads with pac1209x springs and my crower 8mm shaft rockers don't have control issues at 8000 rpm with pac 1529 springs.

Sounds good 👍
Looks and reads like a Soft Solid roller or a Wanna be hard Hydraulic roller...try 8 mm studs with something with Some Aggression. Spring rate and the open Pressure tells me that Cam isn't trying to kill nothing in a 8mm stud
It's a Cheap Option for 7/16ths studs using the rockers I did.
