We have developed a great combination of cfm and port speed on these and have seen great results on torque gain and power production when with fully supporting mods, along with better flow characteristics we have also addressed the reliability problems some of these suffer with valve guide wear and valve seats dropping. our seats are also all cnc cut.

our work is done on a provided head we do not supply a core, all heads are pressure tested for cracks or defects prior to work being carried

Price is quoted per head

will include new valve seats guides and steam seals
