Hi All

Im looking at a set of Yella terra ST2032 non adjustable roller rockers

The factory rockers are very badly worn, lipped and scored, and previous owner broke 4 alloy bridges, in removing.

 

my question 

1 any views on these as a replacement for stockish engine ( std valve springs)

  new Cam will have around .480/.500 lift , so not huge

2 shimming required or straight bolt up

3 will they work out with factory pushrods 

 

thanks

I don’t think non adjustable ones exist muzz. You can get brand new stock pressed rockers, which would work fine though you also need bridges. Otherwise you can get post mounted roller rockers and fit guide plates for the push rods. Otherwise you can get shaft mounted roller rockers which are dearer, but you don’t need the guide plates. They should all work with standard pushrods, but then new thicker walled pudhrods should only be about $150 a set for V8.

$703.98 for a set is the best price I have found so far from this mob. https://outlawspeed....WQUHsJLvGY7YVIK
