Head Crack Between Cylinders 2 & 3

[TheDude]

Pulled the head on my 29' - it's a stock head and the car hasn't run since 1998. I'm just trying to get it back on the road. There is a crack between cylinders 2 & 3, but it runs all the way to the stud hold on one side. I the machine shop said they couldn't do anything for it and wouldn't necessarily be worried about it, but I wanted to get yall's take since you've probably seen it before. I also had some gunky and stuck valves that I've got working now, but how would I know if they need to be lapped? Also, the cylinder walls seem to be in decent shape with not pitting. Thanks!
