Who is running stud girdles? Can you tell me which valve covers you are using?

I am trying to keep the stock PCV system from the factory TPI set-up and was wondering if anyone else has done the same.

You will most likely need the tall covers. Just get a baffle, and grommets, and use the PCV anyway. Ive done it, and I use the Brodix valvecovers. If you must cut a hole in a set that does not have them, I believe the popular diameter hole is 1.22 inches. You can get virtually any size grommet from any auto chain store. The HELP grommets are the ones Im using.

Centerbolt or perimeter bolt valve covers?

Just wondering, why do you want to run a girdle?

Yea, If you are not running a solid roller cam, dont waste the money on a girdle.

Or a hydraulic cam with a lot of spring pressure. Takes the stress off the studs.

I'm running girdles,but I'm way up there on the cam,(well over .650 lift),but unless you really feel you've got valvetrain stability issues,don't bother.They are a pain in the A##!.If your up there on lift,but not just stupid,upgrade to larger studs.

Why are they a pain in the rump? I have a big cam too and a co-worker says I need stud girdles or the studs will break. Is there a way around this?

Put in a smaller cam. You could also install 7/16" studs designed for a SBC and upgrade the rockers to SBC rockers for the 7/16" stud. BBC rockers and studs won't work.

I run stud girdles in my BBC. The girdle helps keep the rocker studs straight. My valve springs have around 200 psi closed and over 600 psi open. That puts a lot of stress on the rocker stud especially when I spin the engine to 7000 rpm. My BBC also uses 7/16" studs.

The rocker nut is replaced with a special longer one that the girdle clamps around. You need tall rocker covers to use a girdle since they won't fit under a stock height cover.

They're a pain because first of all you need enough room to run a tall rocker cover and not all cars can do that. They're also a pain if you're adjusting valves a lot. The girdle needs to be loosened off or removed before the rockers can be adjusted.
