WOW 180°off! You got a stumper. I all the ones I've seen have E & X on the exhaust side and a F & S on the intake side. Maybe stands for Exhaust and Fuel/Start? The J I've never seen. |

I'm stumped. I saw some with an S on them. Could be a mfg. MT may be Meitian, J-Jincheng.  |

Maybe a difference between 64/69 vavle length? Just a guess, I would say different manufacturers. At least it's not Chinese stamping. Lol

Maybe cause they're Honda copys and Honda ships to alot of countries that use a Latin rooted alphabet and language? If I remember correctly 23 of the 29 known alphabets are Latin based. |

I was thinking what dude had said about the valve lengths But then i saw I had 4-5 different rockers with different stampings on them. And i did not think that they made that many different heads with all those valve lengths. So now what? Somebody has to ask the mfg I guess! Hoy Chi Min!
