The inlet manifold that I have doesn't have a fitting for the coolant line to the heater.  It appears that one option is to add one to the firewall end of the manifold but, the casting is rough on that end and should be milled flat before drilling and tapping.  The other option would be to drill and tap the head.  There is a boss just behind the #4 inlet that is part of the outside wall of the waterjacket.  Could I install the fitting in this boss or would it be better to fool with the inlet manifold?
