Hi, i found some cheap sti heads for sale. Will they fit my 94 SS? How much better do they flow than my heads? Also, will the clutch fit from the car? It was a six speed. Thanks

USDM STI heads will not work electrically with your stock ECU and harness. You would basically need to upgrade the system to USDM WRX or STI spec.

6 speed clutch will not work with a Legacy SS 5speed.
