I need to know if these rotor housing are still good to use

The only problem I see with this one is the small cracks near the spark plug hole

This one also has the small cracking but also some pitting. Would jb weld be able to fill in the pitting?

cracks = overheated

Measure them... most likely warped..

straight edge and feeler gauge. ever seen it done on a set of heads? same principle.
