Not sure if it would help but I’d disconnect that Vacuum Line from the Carb to the Distributor and plug it off. My 48 2A runs beautiful and I don’t have that..I know you have a strange Distributor in yours but maybe you’re sucking Fumes & Oil from the Crankcase? Worth a try before tearing the Head off again..also, the Throttle spring should be attached to a tab on the Carb Stud..couldn’t see if you just stuck the Spring under the carb mounting nut? Gotta torque that Carb down to around 30-35 ft lbs..You’re so Close!! Keep Going 👍 Good Luck 🎉
one easy thing that could be tried before actually removing the head is to back off all the nuts and then re-torque them in sequence in a couple of stages...this might just re-seat the head gasket.
a compression test might indicate what cylinder is causing the problem...after the head is off, clean around the base of the studs really well and use a magnifying glass to check for possible cracks...with the studs in, any cracks have a better chance of being widened so you can see them...check very carefully around the stud between the number 2 and 3 exhaust valves...it's a common failure point (my engine is currently cracked at that location)....the excessive ticking sounds a lot like the valves just need to be adjusted....you can also crank the engine with one spark plug removed and see if water blows out...repeat for all 4 in succession...wear safety glasses as whatever is coming out of those cylinders is doing mach 2....fuel vapor and all it's inherent dangers will also be coming out...my guess is it's the head gasket.

thanks I appreciate it. I'll check out those things.

Thank you, I will take a look.
