We currently have an Evo 1-3 cylinder head which we have done the following to:
Stripped and acid dip cleaned.
Hardness and crack tested.
Removed standard valve guides.
Ported and polished head.
5 angle valve cut.
Surface milled head.
Cut valve seats.
Fitted bronze valve guides.
Fitted new valve stem seals.
Fitted heavy duty valve springs with titanium retainers.
Fitted 1mm stainless oversize valves.
Price: $3,500.00 or ($3,000 on exchange for standard and complete Evo 1-3 head in good condition).
We flow tested the head and it has an 18% increase in flow over the standard head at full valve lift.
Please note that the price does not include camshafts.
