So, do suspect a bad head or head gasket? Have you tried a leak down test yet?

EDIT - I totally mis-read your post! Sorry! :mrgreen:

Sounds like the motor ran fine before I would suspect the intake gasket didn't seat properly or over tightened. What did you torque it down to? Did you follow the recommended pattern for torquing it down. Usually from the inside bolts to the outside bolts. The white stuff can be used just on the bolts that would be in contact with coolant.

I just found this quick online as I don't have my Haynes manual with me. Here is what I found quick did you follow this procedure when installing the intake or similar?

Start from the center and go across back and forth.
First pass tighten to 26 inch lbs. (3 Nm)
Second pass tighten to 106 inch lbs. (12 Nm)
Final pass tighten to 11 ft. lbs. (15 Nm)

Sequence to follow when tightening:

Did you reuse the intake gasket from the original motor?

What color is the smoke coming out of your tailpipe?
