Which rocker arms?
Not to knock Jegs, as I have run a lot of their stuff over the years, but I'd steer clear of LS rocker arms from them. They might be made by Harland or Scorpion for that price, but if it's anyone else, who is it? Building a decent aluminum bodied rocker for a low price has been a bit of a unicorn for years...
Only $30 cheaper than Scorpion or HS.. Kinda expected Jeg's to offer more of a price differentiator unless they were to "leak" that they are actually re-badged versions of a known-good design.

Think I am going to get the trunion kit and try my luck there. Maybe by the time I start seeing valve wear I'll have recovered from the build $$ wise and get valves and some RRs.

I saw someone on here... maybe Erik @ HKE saying he had seen like 4 returns on YTs over the years but in the 10 Scorpions he used, like 6 were returned broken. He said they were super light, which probably contributed to them exploding. I believe that was pre-redesign.

I haven't seen a new revision break yet. I do however like knowing if it DOES, I literally have a direct phone number to the president of the company. Again, American made.
But yes, I'd go stock trunion upgraded first, unless I just couldn't for whatever reason.

I was gonna use the stock rockers with the BTR trunnion upgrade kit until I saw the ".638" on my cam card. Honestly, if it was no more than like .580, I woulda stayed stock.
Having said this, the Crower rockers are a serious piece of manufacturing artwork and I'm certain it's a better rocker then any other at any lift.

Without spending $1k, it's looking like trunion upgrade is the way to go. Car has been running stock rockers with stock trunions for 35k and 6.5 years as is, with countless track passes. Just felt like it was time to put something a little nicer in there, but can't justify $1k for it heh.
Thanks for the input everyone.

I run stock rockers with .650 lift. 145 seat and 410 open. over 10,000 miles on the setup and its a DD that I will drive over 300 miles one way to events. My pedistals have been milled to change the geometry by Dennis Wheet at AFD.
I'm very aware of getting a better wipe pattern with roller rockers, but I've tried on more than one occasion with YT 6645 non-adj. rockers and found out the hard way I 'd prefer to sacrifice a better wipe pattern for rockers I feel I can trust not to break!
I looked hard for a good RR option, and considered the Comp Cams Ultra Pro Magnum until I realized they were only offered in a 1.8 RR, and I couldn't find any info that would have me believe the nose weight was as least no more than with the stock rockers.
IMO, you have to pick your poison ( poor wipe pattern, nose heavy, poor/questionable durability, or high cost) !. Can you guess what most will pick, like I did?

I run Harland Sharp roller rockers on my junk. I have used 1.7's and 1.8's on the same engine. I noticed that the engine seems to run smoother at high rpm(6300+) with them.
Surprised no one has mentioned the set-up I used: stock rockers with an upgraded trunion by CHE Precision. I've had no problems. Seems more popular on the Corvette forum, for some reason.
