Does anyone do anything to their VTEC cylinder heads when boring their blocks out? Since the head stays at 81mm how does this affect combustion? Is there machining which can be done to the head to match the block or is this unnecessary?
yea , you can unshroud the valves a little more and open up the combustion chamber. someone else chime in who knows a little more than i do about it
