    How much smaller are they. In use did it actually make enough difference, or still touches.

    huge difference the AC's actually hit 1 header tube, and I couldn't get wires on 4 more these fit with wires and room to spare, I can take a pic of one of each side by side

    The accel shorty plugs are definitely the shortest I've seen but the NGK V Power are pretty short and they come in a good variety. I had some AC Delcos that the end of the plug touched the header and with the NGKs not only did the boot fit, but I was able to route all my wires under the header flanges.
