gen v

this engine was in the truck when found. i matched gaskets that were installed, i again took it down and it is possible that it is wrong. i saw that the larger passage hole at cylinder 8 and cylinder 1 were not open. question? are are water passages to be open? i can not see any defects in the head nor cylinders

engine trouble

got heads back from shop no appearent defects. inspecting head gasket , the front two openings at clynder 2 are closed and only the small square at cylinder 8 is open. all tear drops are open. could one open the other openings for more flow. this truck is runnig a 180' thermostat.
