Impreza L, LS, LX, Brighton, etc.
I was doing maintenance on my ej18 and noticed my heads looked mismatched, and look to be off a different ej, anyone know what heads these are? The right one has a "55" stamped in it, and the left one has a "50" stamped in it, still sohc, and it's a 94 Impreza l if that makes a difference. sorry...
