OK, so I searched and found lots of answers on this topic. Is there a link to something that shows step by step the process for checking this? I have stock ported heads and I have all kinds of valvetrain noise I want to get rid of. The block is a Grooms level 3 block but the heads are stockers.
From what i gather these are the steps to find my desired lifter preload, correct?:
1) I would remove the rocker arms on one of the heads.
2) Remove 1 of the pushrods
3) Insert the adjustable pushrod, making sure it is adjusted first to others in lgth
4) Reinstall the rockers and torque to specs.
5) Manually turn the engine until I get zero lash on the valve being checked
6) Screw out the adjustable pushrod until it can't be adjusted any further
7) Record the measurement and add .035 to it
8) Order new pushrods to that length
Sorry, not really an expert in this area...please provide input if you have it. Thanks.
