Tick Tick goes the magnum.

I just noticed your location is Twilight Zone. Lol.
A video never sounds right. Hard to tell what is normal and excessive that way.

Less chatter from shorter pushrods does not make sense unless the noise is all from the valves hanging open popping through the intake, running into retainer to guide clearance issues, or maxing out and binding the rocker arm travel. You may need to have someone get a fresh set of eyes on it, and not just local joker.

hahah yup the twlight zone AKA Los Angeles i seen on the magnum swap form the wrote this about lift with factory heads, i did use the hughes spring and retainer kit

There is a persistent rumor that the Magnum engine will not tolerate camshafts with higher than .520 lift due to retainer/lock to valve guide clearance issues. This is not true. While max lift is related to cam duration and other factors, we are using a .550+ lift cam in our shop car, did not need to flycut the pistons, and have more than the minimum clearance.
