Quite some time back, Jim Miller identified a mis-match between the water pump and the timing cover that could not be easily seen in normal assembly. He believed it to be the cause of the left head cracking that he found.
The only way to see this is to compare the water pump to the timing cover off the engine. I did not see it in the two passcar motors that I tore down.
Those yielded a pair if G and a pair of J heads. My visual inspection (that has not yet be proven wrong by an MPI) did not locate cracks in those.
