Tech Adept
it will work, a nova plug is longer than the os 8 but it wont cause you any problems from being shorter. you can also try the odonnell 99 if you can get them. it is a long plug and works well in the nova.

Never liked os plugs in the nova motors stick to mc9 or a mc59(hot). They will work perfectly if you cant get a nova #6
