Default 1.95 Yella Terra Rockers

There are 1.95 Yella Terra Rockers for sale on clubgp for $250.00 shipped. Comes with pushrods, pedistils and reusable rocker bolts.

Im more interested in these then the 1.9 modified zzp rockers, because the 1.95 is a higher ratio and should give me a little bit more power.

Is this a good deal, or am i overpaying?

i plan on putting these on with a 3.4 pulley and doing a dynotune from zzp.

That'* a very good deal. You will want to ensure you change the springs to Crowe Cam 105#.

Great deal. Don't forget the modified retainers as well.

Some say i should get 90'* and others 105'*. Im guessing you guys stay away from 90'* because in theory it puts more stress and wear on the tensioner?

Recently a friend had a 90 break. The 90'* are LS6 springs. Doing further research he found that the Vette guys are constantly breaking the LS6 springs. Therefore the 105'* seem to be the better one to choose.

I suggest the 105s. I've had to fix 2 broken 105s on a friends car, but I think he has a bad set. He'* getting a whole new set.

Dan... He probably bought them from ZZP after Comp Cam'* moved their production to Mexico. Anything produced by Comp Cam'* in Mexico seems to have lower quality standards.

Most of the vendors are now using Crowe Cams springs w/o any problems.

This brings up a good topic. So if I bought a kit like this. All I have to do is swap out the valve springs, retainers, and throw in push rods and bolt on and go? Or is it like on my 5.0 ho where I had to figure out what length pushrods i needed and the shim size? Any shimming? Or just torque them down to 30ft lbs or so and go? Is there any up keep on these over stock ones?
thanks
