To change out to pre 95 style injectors you have to change out the fuel rail, and to make it fit you have to change out to the pre 95 lower intake, and then you have to have pre 95 heads for it to bolt up... basically you have to change out everything but the block. However Fred did tell me he's got 93 ported/polished heads due to a bad overport job on his 95 heads because the machine shop was unfamilar with the different design. So it may not be too much more work for Fred's engine...but for other 95's it would be.
