87 rebuild kit on 4x4

Looks like the 22R in toy is in need of a rebuild.
number 1 cylinder:
dry 120, wet 150
# 2 cyl
dry 0, wet, 0
#3 cyl
dry 160 wet 170
#4 cyl
dry 90 wet 90

The best place to order (and help with) a complete engine kit. Looks like I might need a new head as well. This one has been welded up twice. Seems to crack every 80-90k miles. And need new oil pump and timing stuff.
So point me in the right dirrection guy. I don't klnow yet if I need to bore. It's been 40 years since I was in a complete motor tear down.


Thanks
