Hey there, I don't have access to the technical service bulletin on the problem with the cylinder head cracking between the valves. I have crack that extends a whole inch from the seats. Is this normal, or do I need new heads? Running an 89 EA82 SPFI. Thanks in advance.

they can go all the way down to the valve guides if they like to, no big deal. the heads on the RX were like this, and we ported them and have over 10,000 miles on it since the port. you can take a punch and kind of smoosh the crack and close it up a little.
