hi can anyone help me with some techno info please! i would like to know if a set of 1994 legacy twin turbo cylinder heads will fit a 1994 impreza wrx jap import model which has hydralic lifters, as a direct replacement using the impreza cams,lifters etc or are they totally different in design? any advice taken,thanxs.

 

Should be Ok in my opinion. You'll need to blank off the oil feed and returns on the nearside head - the ones for the second turbo. Otherwise I'd fit them straight on. The cams from the twin turbo will do, as there is almost no difference worth mentioning between the lift and duration of any of that era.
