If it has a removeable exhaust cover between the cylinder heads, it's a crossflow, if it is a solid block between the heads it's a looper. And the 85 140 looper is a TOUGH SOB to get running right. I gave up on mine after the 3rd time rebuilding it for melted pistons, and upgraded it to 86 specs. No more troubles after that except for needing to jet the carbs differently to make it run right at idle and off idle.
