So update, although it runs super nice no ticks, I have noticed that it stumbles a bit on start up. It didnít do this before (with the ticking) but now it seems it does it every time. I set the timing to 6 degrees BTDC where before it was 8. Iíll go back to eight but I canít see how 2 degrees will make it stumble upon every start up. Thoughts?

The best way I can describe it is doesnít fire up nicely. It takes several seconds before the rpms comes up to the idle rpm. I will say I advanced the timing from 6 to 8 and it does seem better.

@Frotosride: great description for adjusting rocker arm, really great. I just did this operation last week and watched videos and read lots of posts (yep, lots out there) but your description was the best so far. Wish I read it before I adjusted rockers. In any case, thanks for the concise and accurate info. Unfortunately, after I adjusted the rocker arms, the ticking noise came right back and rockers were loose again (polylock was tightened). Suspect collapsed lifter. Off to investigate more.

I'm sure you have a YouTube account, so upload a video and put a link here. it will help everyone if we can hear it.

Thanks,  If it can be simple then make it and keep it that way. I do it as second nature and it goes quicker than me trying to type it all out. I'm glad it helps.

Unfortunately, after I adjusted the rocker arms, the ticking noise came right back and rockers were loose again (polylock was tightened). Suspect collapsed lifter. Off to investigate more.

Could be a lifter, polylock/stud or rocker arm. For me if it's a lifeter i treat them like brakes. Replace everything at the same time then no worries and the intake only comes off once...hopefully.
