340 X heads cracks between spark plug hole and intake seat

I just talked to the machinist and he is going to pressure test them, if they pass he will install all new seats in all the intakes. The heads have brand new bronze guides so that should all be good, for those that are asking. The only reason I am going through the expense is that these are some really nice old school ported and polished heads, the work that was done on them looks great, a lot of time and energy was spent by someone who knew what they were doing on these heads.
