They look pretty good to me. Sounds ok too. They are 1.7 rockers so make sure you get the right valve springs with the hotcam or you'll break a spring or retainer.

They seem cheap... and my rule is you get what you pay for.. those should be 200-300$.. so idk?

Interesting. The bid is for 1.6 ratio rockers but the ones shown are 1.7.

I'd try and talk to someone about them before buying them. Make sure you know what your paying for, it is your right.

You'll need guideplates for them to work, since they're not self-aligning.

Those will work. You have to have hardend pushrods or those guideplates will cut into the pushrods. I bought a set on this forum for like 50$ w/ guideplates.

Make sure you get the correct valve springs for the cam with the rocker ratio. Then i'd consider getting hardend 7* locks and retainers, i broke a stock retainer and dropped a valve in the motor, i think i spent less then 100$ for comp cams parts from jegs. Worth it, trust me!

Don't buy this el cheapo stuff.....Those rockers are austalian I think, another company has the same type made in china, I would stay away from cheap knock offs. You really be in a situation when they fly apart......

I would pass on them. If you want a budget set of rockers, I would look for a name brand used set. Plenty of people selling them on here. Also, I wouldn't use a 1.7 roller rocker if you have plans for a cam upgrade down the road.

I am converting to 1.5:1 Comp pro-mag RR's. ($268)
Comp 7/16 studs with larger hex and rolled threads. ($68)
Guide plates from summit ($15)
7.3" 5/16 dia. C_moly pushrods ($86)
Converting from a Crane 3/8 SA RR that are taking a beating from a CM cam 321/240 .538/ .558 lift with 1.5:1 ratio.
The standard chevy guide plates do not fit an AFR 190 head (Valve spacing wider). Trying to modify them now. Are there any documents on this mod???
Those valve cover pics really helped. Thanx.

I'm curious, why are you swapping over to 1.5 RRs? Your stock rockers are a 1.5 ratio as well.
