Oh, yeah! It's called "indexing" the sparkplug.
On combustion chambers where the plug is off to the side, like what the SR185 has, the ground strap should be closest to the edge of the combustion chamber. The end of the ground strap should be pointing to about the middle of the combustion chamber. The idea is like the cut back ground strap, where the ground strap does not shield exposure of the spark to the compressed air/fuel mix.
Another theorey is to point the end of the ground strap toward the direction of the swirling intake to scoop up the fresh charge with the plug. You need to know the direction of the swirling intake charge.
It may be worth about .02hp on the SR185. But hey, it's free and all part of blueprinting the engine.
