On my 1963 426 engine, the nipple closest to the distributor is curved about 45 deg toward the driver's side, and the other nipple is longer than the later RB engines I have. They look like they've been there since day one, but I can't find any pictures of other Max Wedge engines that clearly show these. Does anyone have any info on this? Maybe they were replaced early on, but this engine still has most all of its original parts (including the water pump), so I would be surprised if they have been replaced. Thanks for any help
