Yes cam timing is easy corrected. All that's needed is a couple of dial gauges and some brackets to hold them. The K series engine is much easier to get an exact TDC on the dial gauge, compared to the overhead valve engines I used to optimise.
Any K series engine could well be improved with accurately set cam timing. I've seen them 4° or 5° cam degrees out, which is hardly going to provide optimum performance.
Offset pins are available for this purpose.
I used to set the timing accurately, then drill a locking pin location in the correct place. That way the timing was easy to set at a later strip down.
I've never bothered with verniers for cam timing. They were always well over the budget available. I figured that better pistons and bearings were a more cost effective mod than the ability to change the timing a few degrees. If a piston fails, the engine was basically scrap. If the timing is out 1 or 2 degrees. Nothing to serious is going to happen. So I would spend the budget, in a place where I got the best value.

- they are all usually out on one cam or indeed both - more often both. Perhaps some of the more very modern vehicles are better ? - probably not as the tolerances are quite 'generous' ...
