Im using some pro comp rockers. Any feed back on that brand of rockers? I was reading on other forums and not to many good things said about them. Any help would be appreciated. What brand do you guys recommend?

Just walk away, junk.

What is your build? What type of spring pressures are you running?

Something like that you cant go wrong with any of the major companies:
Howards
Harland Sharp
Crane Golds
Comp Cam Golds


Im assuming a 7/16 stud is being used and you want full roller? I like the Howards Purple Billet Alumin Rockers for the Price, you cant go wrong. They are American Made with a lifetime warranty and rated to 900lbs of spring pressure/.900 lift.

Comp Cams Pro Mag rockers will be fine on a 23deg SBC build. If your running more spring than those can take you probably have the wrong head for that camshaft anyways.

They are shaft mounted rockers with solid rollers
195-220 pressure just sitting 500-550 wide open. If that info is any help.

I've been using Comp Cams Magnum steel arms for quite a while, and never had a failure. I use a 7/16" stud, and I use a stud girdle.

Another American company is coming out with some quality stuff - Scorpion. I'm using their valves, but haven't taken the engine apart to see how they're doing.

Pro-Comp is cheap off shore copies of American products. I don't use anything from them. Never buy cheap parts, they're too expensive.
