i was wondering if type R valves would fit into a 1st gen B16 head because i read the valves have a smaller stem diameter and are lighter and i also read all B valves fit in any head. so i guess my question is if i got Typer R valves what would i have to do to put them in? just get smaller valve stem seals and get the 45* resurfaced?
