I have used a block which has had the crack for 15 years.
This block was bored to 80 thou oversize in the 1980's , I only stopped using it when the cylinder walls got so worn I could stuff a 25 thou feeler past to piston.
This engine was thrashed up to 6000 RPM and did the 1997 JOGLE and did a few Hillclimbs
The block got changed two years ago for a better one.
I used to go through head gaskets a bit more frequently, I ended up using gasket goo to sort the problem the centre stud was also helicoiled and goo for good measure.
As long as the top of the block is flat just use some gasket goo and carry a spare head gasket and water.
When you find a better block get it bored new pistons, valve guides replace all the studs and you will be good to go for years.
