Ok, at TDC #6 valves are moving. Went through and adjusted each valve to no lash and about 3/4 turn, or as close as I can. Cleaned and gapped plugs again, hooked up the vac advance and started it.

I was able to see change in vac as I adjusted fuel mix and lower the rpm way down. Timing light is basically on the 'triangle', which I believe is way advanced. Vac pulling 22lbs. Has a loud clack, but definitely sounds better. I suppose next step should be to fine adjust timing with a test drive, but is there anyway to figure out which valves are making the noise?
