what would it take to put on GT40x heads. Headers, plugs, valvecovers,intakespacer or what else. the car is a 94 gt . Thanks for the help!

you dont need anything except for different sparkplugs. everything like rockers pushrods valve covers ect. will all switch right over. you will need to buy new head bolts as 93 and newer use torque to yeild and cannot be reused. You shouldnt need an intake spacer.

New head bolts and gaskets. The other stuff i.e. rockers, pushrods, vc's should fit w/o a problem.
