Could you take closeup pics of each dremeled section ( but with enough background for reference and depth measurement) , number the photos by injector #, and put the pics on a cd ? You could sell the pics for a reasonable price and people could imitate the patterns on their own plenums when they have their's off so future plenum pulls wouldn't be necessary for injector problems.....I'd buy one. Does the pic show the final cuts ? Have you tested the plenum on the engine and verified that all injectors can be removed without interference ? thanks.
