I don't like the idea of disturbing the head bolts either although the old shop manuals show just that. When I recently set my 261 and bell housing I left off the fuel pump and manifolds. I fabricated a steel attaching point that used both bolts at the fuel pump location on the block and then another using two manifold bolt holes at the rear of the head. This gave me two good diaginal attaching points and the motor went in easily with a tilt mechanism attached to these points. An old bed sheet kept the chains from scratching the fresh engine paint. Once the motor was set in went the fuel pump and in./ex. manifolds and I was good to go.
........How I did it anyway
