what heads are there, model, they came off my v4 wrx import MY98

looking for one, cant find one anywhere. all otheres have larger rounded edge square for spark plug, mine has more rounded diamond.

need 2 kno what they r 2 b more specific 2 find 1.

 

The head shown in the pic is a Version 3 ~ 4 head and should have RH-B/LH-B stamped on the exhaust header side of the head.
The heads with a square'ish plug hole are Version 1 ~ 2 heads.
