John, do you have any idea what year your kit is? Do you know when it was first registered. One more nosey question, as long as you don't mind, would you take a couple of measurements for me?
How long is your air cleaner and how far is the back of the head from your firewall? You can probably measure the closet point on the block to the fire wall too as long as I can tell what area you used.
As far as the
oil and water seeping together hopefully it is nothing more than a head gasket or even an intake gasket? When you took the heads off did you notice any/much
antifreeze in a cylinder? If it aint that easy you may have to reinstall and then pressurize the cooling system. Hope not.
