You should use solid wire type plug wires, length (equal or otherwise) on these is not critical.

Burned points is usually the condenser.

The seized tappet bearing is a Holy Crap! moment.
If the roller on the end of the lifter is what you are talking about you have a SERIOUS problem.
You say seized, I have never seen one seize, I have however seen many explode.

If this is what happened you should consider a complete teardown.
When that happens it wipes out the cam and the lifter holder.
The really evil part of this failure is that the little bits of super hard metal that come off the roller and the needle bearings and the camshaft go through the entire motor and spoil it.
The pieces shred the oil pump housing and get pumped into the oil tank where they have the chance to make a return trip through the motor.
The little bits get stuck in the soft piston skirts turning the pistons into sandpaper, dragging up and down the cylinders when run.
The super hard little bits go through all the other bearings in the motor and make little micro injuries that eventually turn into major catastrophic and premature failure.

I noticed that on my dual fire ironhead. Put your hand down at the end of the exhaust,feel the differ between the two exhausts. front is running a little warmer. Its the first to foul out too. the rear exhaust ,that is. Will put a little more time on center the points. I think it would be wise to kept a log book for your bike. Everything parts #s,measurements,brands,how it was installed and when. Got me one of those temp gun too. very inexpense, fun.

Some factory cams have different grinds for the front and rear cylinders.

Center the points cam, this is critical as it changes the spark timing.

Adjust the valves properly, from there it is what it is as long as you have no vacuum leaks.
