A load of my mates were in to Banger & Hot Rod Racing 'The Bexley Suicide Squad' in Mick's Hot Rod the Ford Pinto lump had such high compression we painted a line on the ceramic in line with the electrode so when you put them in it had to face within the top half because if it faced down the piston tapped the electrode shut :)
No that's how Dave at Boss Racing used to build them for Oval Track racing , I remember he used to put the con rods in back to front as well for faster rev pick up, trade off was faster wear but they were rebuilt often enough anyway. :)
