go to v6power and take everything off of the list on that link that mustangman posted, Most of the wiring harnesses will work, I think you want to use a 93 cobra TPS, and then use an XCal to tune it all.
Its not easy, its not bolt-on, and I think your heads also have smaller bolts and a little bit different of a bolt pattern, as in 1 or 2 bolts will not line up, but it should seal correctly. Otherwise get SC heads or earlier NA heads.
Honestly, just do a split-port swap and then get a power adder after that if you still need something to go faster. An M112 SC would be easy to mount on a split-port engine.
