Cylinder Head Removal

Beginning to disassemble the engine. A previous owner had converted the motor to a single carb with the intake manifold appearing that it could have been fabricated by the builder. This manifold is held on by 3 Allen screws. What is interesting is that in both the shop manual and the parts exploded view, 4 bolt holes are shown attaching the intake manifolds for dual carbs. Don't know if 3 was a production variation or if the builder filled the inner pair and then drilled and tapped a single center bolt.

The Allen bolts retaining the manifold easily came out, though the center one required that I cut down an Allen wrench, ruining 3 hack saw blades in the process.

The bolts and nuts securing the cylinder head came off easy enough, except #1 in the tightening sequence. In the picture below, the bolt head on the right.

 

 Most of the fasteners showed evidence that lock-tight or similar was used on assembly and I suspect for #1 that this is also the case. Due to the location it is difficult to get heat on to the position in the cylinder where the bolt is threaded. I'm more afraid of stripping the bolt head than breaking it off. I'll try it again tomorrow with more heat and a hand impact tool, but I need to get the proper size impact socket.
