Use the A&B epoxy from Edelbrock or Morosso - doesn't matter, niether of them actually make it and they both buy it from the same supplier - it is about $25 for two big sticks (about 2 pounds or so) It is plenty to do your head two or three dozen times (in case you screw up)------------------------------------------

______________________________________________
Edelbrock A&B EpoxyA universal filler.
These two-part bonding products mold like putty, yet harden in one hour to a steel-like consistency. They don't shrink and aren't affected by solvents, oils, or gasoline. The maximum temperature they can withstand is 250 degrees F, which makes them perfect for repairing intake manifolds, cylinder head intake ports, heads, and blocks. They can be drilled and tapped when hard, adhere to almost any clean surface, and harden in 60 minutes at 75 degrees F.
