Reply to "coolant leak???"

Sometimes the two threaded holes (one is 3/8-16 and the other 5/16-18) in the front of the head pierce the coolant circuit. It's not uncommon due to a little core shift in the water jacket core. If so it may just be a little temperature induced expansion of your coolant back through these holes. You may want to add a little sealant to these screws when you reinstall your intake or you may end up with a coolant leak throught the screws.
