hey guys i just bought an rb25 head, the bloke i bought it from is adament he saw it running on the motor in an r34 gtt which has him beliving its a neo head, however when i pulled the exhaust cam out this morning the lifters had oil holes (presumably) in them which makes me think its an r33 head. i dont mind either way but he said it was a neo head, i havnt got any other parts for it yet that i can compare with, i have so far only recieved the head with cam gears attached. he also said its had the r33 cam covers put on it, which i assumed were the same as the neo anyway bar the valley cover, which is a 33 item with the twin cam 24 valve thing on it..
can anyone tell me what i have as im pretty sure now its a 33 head..
cheers
