Nice to know you are smarter than everyone else.
Thats not what I said.
I'm as smart as any of the guys that ACTUALLY do this stuff daily for a living.
Its literally part of building any performance non stock build engine. Do you guys really think this stuff is just bolt it together? Don't check anything and it will run?
Erics posts lean towards helping the novice engine builder. You and I may know that most things need some work. "Bolt on performance " is a myth. I didn't see the need to insult the man on a public forum.
I agree, mt might have been a bit harsh, but it was hard to watch. First off, those are high quality rockers. I've used at least half a dozen sets over the years, with zero issues. I've mocked them up on just about every common sbc head out there, Dart Pro 1's, Brodix Track 1's, the same chinese knock off he used in the video, RHS heads, Profiler 195 and 210 heads, World Products sportsman 2's, afr 195's, which means they will work on other afr heads, and even stock gm 993's. They will work on all those one way or the other. They are a universal fit. That's why they come with a pile of shims for under the stands, and the bolt holes are slotted. They don't know what head you have and or if you have a std length valve, or a +.100, +.200, etc, which will require a different set up, or which retainers, etc. They are also half price, and are really nice actually.
As far as the video, his gripes made me cringe kinda. The stands not clearing the studs? Really? Trim the 4 studs on each side. I can't count how many times I've had to do that. Many times the stud is longer than it needs to be, and a 1/4 inch or more extends past the nut. Trim it flush, problem solved, big deal. As far as the clearance of the edge of the rocker on the retainer, another one that I didn't understand what the "issue" is. They looked like +100 retainers, so that happens. Also, a simple lash cap will solve that problem, and, no, they won't fall off in your engine. I use them a lot. Obviously you will have to figure out which, or if, you need to run shims, to get the geometry right, based on valve lengths, etc. It's all part of it. As far as the 1 roller tip not perfectly lining up, that will not be a problem either, it will not wear out the guide. It was kinda weird though, how the one lined up perfect, but the other one didn't. That's likely the head, not the rockers. Those were chinese knock off's after all. But, I'd bet half will be perfect and the other half will be slightly off like in the video. BFD. Or add or subtract the shims on the one side to line the 4 up perfect. It's all part of "custom" engine building, you have to do the same shit with T&D or Jesel many times. I've had to modify stands, or clearance rockers, etc so they worked numerous times with Jesel or T&D, and those were made specifically for the head they were on, it happens.
The other thing nice about those rockers, for the money, they are .220 offset, which allows you to either move th port over a bit, or run a bigger diameter pushrod, with no clearancing, and or has solved a clearance issue with the pushrod, without clearancing. You can also run a .180 offset lifter, if you're using solid rollers, and have your pushrod almost back to straight, and it further helps clearance. Not trying to be to harsh on Eric, but I think he should have been more clear. It kinda sounded like a whine fest. They will work just fine. Custom engine building is about problem solving.
