James, to see my ''doc dual plane '' picture go to 65 GS.com, then to the nailhead,,, then to Doc mod intake..... click on the pic of the engine there and take a good look at the intake opening.....
next to see my ''redneck ram air'' go to the 65 GS forum and then to how to's then to rebuilt cold air...... and click on one of the 2 pics there.......
just some ideas......
Doc....
