Thanks. I hope it's only one or both heads, but certain things point to a new engine or at least a full rebuild.

If I recall correctly Mr. Raby considers all overheated engines unsuited for a rebuild. I understand why he would take that stance, but it's all risk vs. reward. I lost 80% of the coolant during the warm-up laps though, so the engine would have been really hot. It may not be worth the risk. Adding to that is that the P.O. has had the oil pump off and that one of the heads was shiny clean and the other not. I also found water pump debris in the hoses when I changed the water pump way back. I understand that this could have gotten stuck inside the heads and contributed to the engine overheating.

Given all this, is it even worth it dismantling it for a rebuild or would you go straight to a replacement engine?

Currently the engine is on the ground but not dismantled. Hopefully I can find out over the weekend, but if there is a small crack it may be more challenging to find and determine the cause.
