Best way to quiet valve train noise on stock FLH

So the things to try are roller rockers, shimmed to spec. Check for clearance issues, Heavy or straight weight oil. And possibly some relief from an Engine oil additive...
Sounds close to the things that I wanted to try. What about the Forged rocker supports? Do they actually keep the valve train lined up better in stock trim too?

I have a friend with a 103 ltd. He's not a fan of the valve train tick that comes with a push rod motor. Enough so, that he's thinking of switching brands. Is there some "tried and true" ways to quiet the ticking from the top end of these motors? Keep in mind that the stock pipes are still on his bike because he likes it quiet. So I doubt cams any more aggressive then 255s will be on the list of things to try..
Any help would be great. I already thought of going to 20-60wt oil.... Would roller rockers help?

P.S. A Goldwing is quiet, maybe there's "a friend" on that forum can explain how they do it.

Zippers performance sells shims to control the rocker arm movement. I'm sure others do also. SM says end clearance should be .003-.013" with a service limit of .025". With the close proximity of the spring retainers to the rocker box and cover, it is almost a given that there is going to be noise. The cover even acts like an amplifier of the noise. You can remove the cover and check clearance between the spring and rocker box and use modeling clay to check clearance between the retainer and cover. Then grind as necessary to improve clearance. Shim rocker end play and check the lifter/pushrod relationship. If you're not satisfied, aftermarket rocker boxes are still an option, though an expensive one.

Hey Steeler
I put 6oz. in the Primary, 6 oz in the trans. and about 20 oz. in the engine. IMO it works great. Engine noise got quieter but what really impresses me is the trans. it shifts much smoother and before when I pull up to a stop I had to rev the engine a little and catch neutral on the way down now I can find neutral with ease. I am sold.

Fresh regular dino oil quiets the tick but that don't last long.
Yeah, it's a pushrod engine.
Sound like the guy is a Victory overhead cam candidate.

I think I'll be visiting the auto parts store and pick up some Lucas Oil additive today. I haven't heard anything negative about using it in combination with Harley fluids.
