Thanks. I have never had a lifter failure in all my years of doing this. The only problems I see with stock type lifters is due to incorrect valvetrain setups leading to instability and lifter guides getting old and failing...

But I wont go into further detail on that unless its warranted and would need to be a fresh post.
The reason for the reply here is Cajun's method is sound for one, "critique". The use of the torque wrench I feel only adds inaccuracy and variation between users. Once the rocker is fully seated/mated to the head, any further rotation of the bolt is only adding stretch to the fastener and not affecting lifter pre-load. I feel the procedure would be much more accurate if people simply hand tightened until fully seated.
