I started this post asking questions about (Bad Driveline Angle) and how to remedy my problem with too much engine/trans angle making the driveshaft run uphill because the valve covers were an inch higher than stock. Thanks to all of your comments and clarification I'm hoping to eliminate that issue. This takes me to a new question...
I ordered new Crower Enduro Stainless Steel Stud Mount Roller Rocker Arms 73627-16. Two adjustable pushrod checking tools, I already have valve checking springs so I can see if changing rockers changes my pushrod length ???

I have been doing this a pretty long time like some of you, but, I do not consider myself anything even close to being a pro.
#1: My question/questions is/are... Per Morel's website, they list my lifters as having 0.120" of preload travel. I read a post from Cliff here on the forum that he runs a deeper preload than a mere 1/2 - 3/4 turn on adjusting nut on his engines so they run quiet. My engine has a distinct tick to it. I discovered that the person who built mine did not put much preload on any of my lifters. I was thinking Cliff said he sets his at about .060"-.070". I will reread his post on that. I want mine quiet also.
#2: Because my cam is hydraulic, can I follow my old way of adjusting hydraulic valves, with certain valves adjusted on #1 @ TDC and the remaining on #6 @ TDC ? Also, because my cam has the 4/7 lobe swap, can I follow the chart I made (see below) to do that?

Hydraulic Valve Adjustment (With Standard 1-8-4-3-6-5-7-2 Firing Order)

Turn Crankshaft @ 0* #1 TDC

@ #1 TDC: Int. 1-2-5-7
@ #1 TDC: Exh. 1-3-4-8

Turn Crankshaft 360* #6 TDC

@ #6 TDC: Int. 3-4-6-8
@ #6 TDC: Exh. 2-5-6-7





Hydraulic Valve Adjustment (With 4/7 Swap 1-8-7-3-6-5-4-2 Firing Order)
@ #1 TDC: Int. 1-2-5-4
@ #1 TDC: Exh. 1-3-7-8

Turn Crankshaft 360* #6 TDC

@ #6 TDC: Int. 3-7-6-8
@ #6 TDC: Exh. 2-5-6-4
