Long story short, I no longer trust the rollers I have and need to upgrade.
It's a 460 w/DOVE-C heads/.576" lift hyd flat tappet cam...nothing too insane.
Any suggestions?
Any brands I should definitely stay away from?

rockers

I've been running the Herland Sharpe roller rockers for 3 years so far no problems yet plus their less expensive than the comps by buddy buys the expensive ones for his drag car and always replacing broken ones he's going to run the harlands next to see if they last for him

Mine were no-name, and they are literally falling apart and the polished surface on the rollers is no longer polished.
Plus, 1 is beat to death from a valve keeper failure.
'nuff said.
This failure has cost me a fortune.
Never again.
The Harland's look good for the money.
You guys use the 1.73 ratio?
I see some with 1.80, but that might be a bit unnecessary.

Comp Cams 1838, but they are 1.8, and then there is the Comp Cams 17045, or even the comp 1411's work good. Hardlandsharp are good, so are lunati. Just depends on budget. Even BBC rockers work. Might want to check ebay.

That's a tough lesson. It's the old buy once cry once thing again.

1.73 here.

While I'm on the subject, there seems to be a pushrod length issue with this motor which may have contributed to the dropped valved.
All the IT guides were worn out/slotted/elongated/whatever you want to call it.
IT only.
All the pushrods in this motor are 8.75" long, 3/8" Comp.
Any body have a similar setup using different length pushrods?

I know it's hard to diagnose this on here, but any info is helpful to me.

Crower Enduro Stainless steel, been using these trouble free for about 8 years. BBC rockers do work but are not ideal, which can lead to other valvetrain issues. The length from the trunion to the roller tip is different between the BBC and BBF albiet slightly, but they are different.
