Just wanted to thank everyone for their help.

Narrowed the noise down to lifters using the hose trick and then used Rislone for about 30 minutes and no more tapping! Changed it out with 10w-40 and it sounds smoother than when I got her.

I did notice when I had a screwdriver on top of piston 1 that I could feel the carbon buildup, does anyone recommend doing a fuel treatment or am I asking for trouble cleaning everything out?

Mahalo and much appreciated.
