Its a very good video but how much 'pre-load' should you put on the lifters? He uses 3/4 turn past zero lash in the video.
I'm putting together a game plan in my head on how I'm going to tackle replacing the timing chain job. Here are my thoughts.
1. Pull all accessories off/out (Rad, water pump, alternator, plugs)
2. Rotate motor to TDC on piston #1
3. Remove lower pulley & harmonic balancer
4. Remove timing chain cover and inspect chain gears/block/cover for any damage and make sure the timing marks line up on the gears
5. Remove gears and use a puller to remove botton gear.
6. Install new Edelbrock #7800 true roller timing chain set. Is a thrust bearing needed or required? any videos I've seen on youtube dont show needing one but they do sell them.

7. Test timing chain cover fitment for any possible contact
8. Remove valve covers and check zero lash on lifters or should I loosen the rocker arms then then set zero lash then set pre-load? Minimum two revolutions engine rotation.
9. If any damage was found in #4 drain oil and remove oilpan and install new gasket. This will also fix the oil pan sweat on the back of the pan.
10.Install new oil pan gasket and timing chain gasket/seal and torque to spec with permatex gasket maker.
11.Install new valve cover gaskets and re-install valve covers
12.Install Harmonic Balancer with press on tool and install lower pulley
13.Install water pump with new gaskets
14.Re-install all accessories (Rad, alternator, plugs)
15.Install new fluids (oil,coolant)
16.Double check, tripple check everything
17.Prepare for startup.
18.Set engine timing and carb.
