What is the most stable springs, shims/spacers or collars on valve train for a 426 style hemi??? I looked on Stage V website at some pictures and the show collars. What's your thoughts on advantages and disadvantages? This is for a 582" all aluminum Hemi .650 lift, 280 duration, 80% track- 20% street.

At that lift the stock configuration stuff is good enough. Stage V rockers are the prettiest and I use Keith Black stands, shafts, plugs and springs.

I have the KB stands and shafts, but I'm using the DLI roller rockers which aren't made anymore.
I have the stock spring and shim setup, although most say the collars are better. My roller cam is only .672"/.651" lift though...no problems at all after nearly 10 years.

Holy Mother of God, get rid of those archaic springs!!!

Thanks for the input. My concern is I bought this motor from a guy that bought it from an estate from a old KOS racer. It was built by a well know builder. The motor was over 10 years old but new(never run and never apart) so I took it apart for inspection and one of the Norris rockers roller tip was pushed off the side of the valve on the retainer. It may have been bump over during assembly. I'm sure glad I caught it. I have no problem buying the collars if it is a better route.

The collar setup may be better, but why change now? I've been running mid 9s at almost 2 tons for 9+ years and just recently dipped into the 8s. I'm not seeing a reason to change anything. The springs obviously do their job on my setup. If there was gonna be a problem, I'm pretty sure I'd have seen it by now.

Buy the Stage V collars with the wave springs and set the clearances up to what they recommend. The Hemi motors really need a very good set of pushrods and valve spring to rev and live If you wanted to race it a lot I would say convert to the Jesel rockers or another brand as good as they are If street and occasional 7500 RPM blast use the good springs and pushrods with the rockers you've got

I thought the Norris Stainless Steel rockers were good. Is that not the case?

You have Indy heads with cast in stands. Not much there that you can change. You can put collars on if you want. I prefer not to.

Norris rockers are better than stock, but that's about it.

Ok, I will keep an eye on them and may switch them out after I get the car running. I just knew Bob Mazzolini use to push them 15 to 20 years ago.

I see weight reduction has high priority with Norris?

An FEA analysis of those rockers would give me a coronary!

Hard to beat Stage-V rockers with good heads and collars (if they are not installed too tight).

Man! I love the look of Stage V. I would want clear valve covers...

What is a good source for the wave washers? Mine already has collars and I would prefer to add those style washers.

Rich will that Stage V setup as pictured fit under a stock black valve cover?

If you wouldn't mind could you PM me the cost of that setup. I will be building a 481 Edelbrock Vic jr head engine , using a flat tappet cam, yet to be determined.

Send me an email (rich@fastmanefi.com) and tell me what you want. When you say "setup" what all do you mean? rockers, stands, everything? or just the collars we discussed?

It's just me... I can't stand half-a$$ed, budget-driven, band-aid engineering.

Using a cheesy spring to try and keep a loaded rocker arm in position vs. a stable method that maintains the correct location on the shaft just strikes me as 1950s OEM technology.

Carry on...

It obviously works fine. Even in some pretty extreme situations...such as mine for the past 10 years. If mine hasn't experienced any issues w/ that setup yet, then I'm sure not going to change now.
