Supersport head-sold on an exchange basis-old core must be serviceable and no cracks--See MSE3 for performance figures-perfect for use with 7cc dish on mega pistons 1380cc. Without by pass but with heater hole which can be blanked off.

See C-AHT135 for a road going version.

Some companies call this a stage 3 head but our way of thinking similar to original Special Tuning is as follows-for 1275 head

Stage1 has 33mm inlet 29mm exhaust std valve sizes and gas flowed

Stage2 has 35.6mm x 29mm ex road quality valves and ported to Road Sport spec

Stage3 has 35.7mm x 29mm ex race quality valves to Super Sport/Grand Tourer spec

Stage4 as stage 3 but with either larger inlet or exhasut valves and more modified throat and port work.

For real race use ask our technical staff at York or Potters Bar.
