Almost sure its not the cam. After my first attempt at the pushrods and finding loose jam nuts and retightening, the motor was quieter, no ticking...Until my test ride tonight, and the ticking has returned. My best guess is one or more rods were not tightened enough turns and are loose?

You're using the SE tapered adjustables, right? How many turns did you go with when you set them? I set mine at 3.5 turns and they have been quiet. Well at least as quiet as the valvetrain ever is on a Harley.
One last thought - if you are going in and making adjustments, make sure the bike is stone cold before making the adustments. Don't ride it, let it cool a little and then mess with it.

I think you need to start over. While many use the tdc method, it must be actually tdc-compression to do it. To make life easier do this. Put the cyl you want to adjust on it's compression stroke. It will blow your finger off the plug hole as it's coming up. Put the piston at it's highest point.
You can at this point loosen and adjust both.
Lengthen the pushrod until all (vertical) play in the pushrod is taken up and from there extend the pushrod length the required turns per instructions. Tighten jam nut and repeat the other pushrod the same way.
Before rotating the engine make sure the lifters have bled down. This will be seen by being able to easily rotate the pushrods.
Set the other cylinder on the top of it's compression stroke and repeat the same process.
The other method some use is to rotate engine until the exhaust valve just starts to open by (viewing the pushrod) the intake pushrod is now adjusted. Let it bleed down and rotate engine until intake starts to open. Now adjust the exhaust pushrod. Let it bleed down and do the same with the other cylinder.
Don't use loctite.

If you're not positive that all is well, start over. I also had an increase in valve noise or 'ticking' when I installed the Woods cam, so it may be that some increase is normal. The Andrews pushrods are different lengths, are you sure you got them in the correct positions? My suggestion would be to turn the adjuster 3 turns instead of the maximum of 4 which is listed in the instructions.

That's what I surmised and how I installed them. I will get back at it tomorrow and readjust them again! Thanks for all your input!
