On Honda cylinder heads we offer a light porting and polishing service. This is a manual service (not cnc) using our specialist tooling.We generally do this service on the Honda B , H and  K series engine but can accommodate other Honda models. We only offer this service when included with the 16 valve guide replacement , this is because we want to offer our customers the best service and final result.

In our workshop we only replace valve guides on cylinder heads which we are assembling , this is to ensure the quality of the complete cylinder head before returning it to the customer and offer the very best result for our customers.
