Cracked exhaust manifold on a '73 B20F 1800 1973

Drilling small stop holes, like 3/32 - 1/8" dia., at about 1/4" past the end of the "visible" crack may help arrest further crack propagation until you can find a qualified welder. In the mean time if you fill the crack and stop holes with exhaust joint paste you should be able to easily drill/grind it out later just prior to welding.
