Quick question: is there an assortment kit for Holley power valves?
They used to sell assortment boxes for single and two power valves for the Holley carbs (4150/4160)

Now that I want a kit of my own, I cannot find a dang assortment anywhere. I’m also only looking for Holley part numbers not others as I’m not sure what is compatible or what is not. (Quick time, proform, etc.)

I see buy 10 assorted power valves on eBay for $100. Much cheaper than one Holley power valve but not sure on quality.

I personally am working on a Holley Street Warrior 600 if that is even needed.
Thanks!

Of course. In Quick Fuel and a few other brands too.
 

 
Thanks Halifax but the kit I was looking for a like the jet kit but nothing but power valves. 2.5-9.5 singles or doubles from days ago. Ever since Holley fixed the back fire issue, I’ve not seen such a kit.
I’m not as up on aftermarket kits that are the compatible. I see quick time has a kit, but they are “4 window” not “2 window.”
So I’m not sure if that even makes a difference.

It was never a backfire issue. Ever. When Colt took over Holley they stopped keeping up with the tooling and **** like that and they started failing.

Of course, the aftermarket decided it was backfiring that was causing the failures and they sold thousands of of those power valve blow out protector bullshit kits.
