CLASS RACER FORUM - View Single Post - Autolite double platinum plugs? Also indexing?

Are they good for a racing application? Naturally aspirated. 13.5 to compression.
I've never used them, but they are a semi retracted tip (half way between the plugs I am currently using and the stock champion plugs) plug with a fine electrode.
They will fit without worrying about the pistons colliding with them.
Also how should the plug face. If I use the indexing washers?
