Fatboy You said you had the heads ported. This could be the problem. It very easy to grind too much out. If the intake was also match proted to the gasket opening, I will bet that there is not enough material to properly seal the ports OR the #1 port is crack and coolant is coming through the port wall. There is not alot of extra materail to grind away on FE heads. You might want, like others have said is pull the intake and heads and have them pressure tested. You are on the other side of the pond. Not sure who you would go to there. We have a couple of guys here that could do this here. Rick L.
