The previous owner of my SVT did a less than professional job replacing the cam when it went bad and did not know to let the VCT flip resulting in valve damage. My question is what are the specs of those valves? And is there any valves that I could get out of a junkyard that would work, or any other cheaper than performance build option? I'd assume the SVT and Zetec don't have the same valves? Thanks for the help y'all.
