The os is a standard long plug Short body. not threads.. They all long threads. Again the plug is NOT the problem. I suggest the Op disassemble the engine and see what really is causing the problem.They are not all long, one of the is an OS #8 which is considered short plug.
since you think the problem is the length of the plug then you use extra washers and fix the problem!
