Hello Ken:

Thank you for your reply.  Only the injectors on the left head were the
problem.  All the injectors were new and were installed in September
2003 along with all new fuel lines when I installed the Boston Bob long
block.  When engine performance problems started about 10 months ago,
one of the things I had done was replacement of the fuel tank (but it
did not help with performance problems).  After right head was repaired
this past December and performance problems continued, I found that the
spark plugs on the left head were fouled.  My mechanic theorizes that
injectors on left head were leaking and engine was flooding at low
speed.
