hello purchased some heads from a member here...after they were being shipped ,,was emailed by member that the heads have minor pitting that was just noticed but shouldnt be a problem...well after i got them i sent them to machine shop to get checked...they call me and tell me heads are junk...too much pitting and they have cracks by the spark plug holes,,also they told me that with seats were cut into each other, they are more likely to drop and cause engine damage....i sent a pic of invoice from machine stating heads are cracked to member and hasnt responded...prior to sendng pic of invoice member was told by mechanics that heads are good...therefore a refund wasnt possible but would send me some a list of parts to cover it???...and to top it off some of the exhaust holes threads are gone need helicoils...would you call this minor pitting??
