I didnt change the head gasket when i changed the cam (in case that is what you were thinking), but it's a Ford head gasket.
What do you mean the cams will have different timings?
The ignition timing was set at 8 degreee's BTDC when it was tuned last week and that is where it remains.
The valve timing was left a 0 on the vernier with the piper fitted so it will only be the cam profile itself that has changed.
