'90 MM 2.4L FI Build

I would sure like to see the crack if you get a chance to take images anytime. Makes me wonder when machine shops give you news you never expected, especially if they had my part for more then a day or so. These Mitsubishi heads are tender in many cases and the clearances between valves and stuff can be minimal. A little off on timing and temperature climbs some time causing a little more stress then usual, pull it into garage where it cools too quickly and the hairline begins. Your not the Lone Ranger when it comes to cracked heads on these things.
My first one cracked after I moved to a freezing climate and left the water in radiator all winter because of a broken trany. Cracked head, intake manifold bottom almost fell out, radiator split, 3 freeze plugs popped. Second head cracked the entire length of cam shaft. 3rd head crack on an over heat that I caught early and pulled right over. Found a quarter size hole under cam shaft area. 4th head..flat tappet has been good so far. Oversized radiator with electric fan and a 180 degree thermostat so cool water starts a little earlier into engine. Keep us informed, Heads are available still.
