Complete S-3 Racing Top End Kit : 2018/2019 GasGas EC/XC 300. S-3 Billet Racing Head unfortunately no longer available with set of 3 different domes for tuning purposes.

Or you can opt for the higher compression dome if you are going to stack additional base gaskets to alter/tune port timing for high altitude or running race fuel at low-moderate altitudes. Price has been reduced due to single dome provided vs three. Increase compression and reduce squish clearance by changing domes. Dome with least clearance gives highest compression.
