Next step is to bolt the cylinder head on and we’ve gone to town on this one with the following mods:
- Full CNC head port
- Supertech bronze valve guides
- Supertech inlet and exhaust valves
- Kelford valve springs
- Toyota valve stem seals
- HKS uprated head gasket
- Lamspeed Racing H13 head studs
The CNC ported cylinder head will maximise the power we can achieve from the engine and will also mean we can get more power running less boost thus putting the engine under less stress.
