No valve adjustment?

Update!

I did my tune-up today. Oil change (Mobil 10W-30 with K&N oil filter), Spark Plugs (NGK ZFR5N with washers removed), spark plug tube seals, air filter, Distributor cap and rotor button.

I also did the fuel line modification, replacing the fuel filter with a proper fully metal one.

So.. the TICKING!

I pulled the rocker assembly, the push rod was straight so I pulled the hydraulic lifter. The head is from ~'64, but has been retrofitted with hydraulic lifters from an '81+. With the rocker assembly off and the spark plug tube removed above that cylinder, I WAS ABLE to remove the hydraulic lifter with a magnet.

The lifter was definitely bad. I replaced it with a new one... but the ticking is still there. I feel it isn't as bad/noisy, but it is definitely still there. On a positive note: the acceleration and idle are much smoother... not necessarily more power, but definitely less stuttering/hesitation. I will be attempting the HEI ignition conversion in the coming weeks, and I'm sure that will help a lot too.

I guess the next step is to pull the camshaft. The bad lifter must have damaged the cam... sigh. Can I pull the camshaft with the motor IN the car?
