Intake question?

Yes, it is an LD4B, I misspoke before. Talked to the machinest and he can do the machining for $80.00 He suggested filling the pits with a skim coat of JB Weld and then having him resurface the intake faces. I am thinking about what to do, I want to powdercoat the intake but want all the issues fixed first. Thanks for the input.
