Ok,
I bought my bloody heads without rockers
I have no idea what I need, Pedestal or Stud?
Also Im assuming ill have no probs with a 1.72 Ratio?
These would be on GT-40 Heads.
I do believe those use te standard 5.0 rocker which would be the pedestal. The stock length pushrods should be close. You always need to check. When you get the rockers on you need to turn the engine over by hand and watch how the roller goes across the valve stem. If it starts at the edge of the stem thier too short and if they try to go off the the stem under lift their too long. If its not correct pic up an adjustable pushrod and play wit hit until you get a clean contact with the stem
