The valve train sounds a little noisy after my first hot adjustment a couple of months (100 miles) ago. Should i stop tightening the nut just after it stops clicking, or should I go a quarter turn after?

Go 1/4 to 1/2 turn down to preload the lifter.
You don`t want to pound out the snapring that holds the lifter together. |

If its a regular lifter, turn another 1/4 to 1/2 after zero lash.
If its a SD455 lifter, stop turning after the clicking is gone. Those lifters are a limited travel design. Street ´69 Firebird. 3800 lbs with driver. 455 with D-ports. 275x50 drag radials. Stock suspension. 11.24s@124.2mph (motor only)10.42s@130.3mph (+150hpNOS)

That's great! I was going to ask the same question this summer when I pulled the car out of storage!

These only apply if you are using aftermarket poly locks on the rockers.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
