Paul,

I could cut ther length on the runner to position the injector block and
bellmouth furterh away from the wall of the plenum but ther runners will not
be equal in length.  How critical is it?

Not critical if you can set the mixture for each runner
differently. Even if the mixtures  are the same you may not notice.
Check the plug color and EGT's..
