I have a 1986 F250 6.9 and I purchased rebuilt heads but when I torque the heads down the intake manifold will not line up with the heads, am I missing something. I bought Felpro gaskets and the heads were rebuilt. They did deck the heads and I was told they took very little off but this is the 2nd set of heads I got from this company I returned the 1st set. If I enlarge the intake manifold bolt holes it would work, anyone else ever had this problem?
