Because you can always find a good running non integral head 250 for $150 or so .
Ergo , the integral engines are not worth the $700 ~ $2,000 necessary to do a full rebuild .
If the cylinders are not tapered you can always replace the worn out pistons and slip in new bearing shells , do the valves & guides , later model integral head engines with the EGR valve already have stellite seats & other unleaded fuel upgrades from the factory .
These are *very* thinwall cylinders by design , back when they were new , core shift in manufacturing meant the side of the cylinder occasionally cracked and fell into the water jacket as you were driving along , not racing or pulling 3 tons up a hill.......
You had to be there to understand I guess
As I said , they're very good engines , light and high horsepower plus torquey little monsters as all InLine engines tend to be , the longer the stroke , the torquier they are .
As long as you take middling care of it (clean oil !) it'll last & last and every 20 years or 100,000 miles or so you simply overhaul it , not rebuild it .
These make the best work rigs unless you need to race 'round with loads , that's not real working .
