When you had the head off you should have taken a straight edge and laid it
across the surface of the head, and the surface of the block to see if they
were flat. I would not have just put a used head directly on an engine
without having the head reworked. the aggrevation of not knowing where your
problem lies would be greatly reduced by investing a hundred bucks in a
reworked head.
