hi.

does a xr6 head use more fuel than a gli/fairmont head in the ed model just want to know.

i presume you need the xr6 cam/head/fuel reg/ecu to get xr6 power??

will just the head give some more power

and will a xr6 cam use more fuel than a std cam

dude you asked that same question 12 months ago..

the amount of money you will need to spend to get the xr6 head,cam,fuel reg and ecu.
you can just buy a wade cam and you will see better gains from the wade cam on the std head..
