tickford head on xh
i have a 96 xh falcon ute. It runs the ed manifold with EEC4. I purchased the ute with a tickford head on it (has a great big T and 94dt stamped on the front, so not 100% sure.)
My questions are:
1. is this a tickford head and would it have a tickford cam?
2. time for the plugs to be changed, so should i be using XR plugs or standard plugs? currently has standard plugs.
3. is the standard xh manifold and computer going to impact on the cars performance, due to a different head?
If you can help with these 3 questions i would be very grateful.
