I have a P90a head (Solid lifters) I want to upgrade with larger valves I have found out that I can increase the size by 1mm on the inlet valve and 1,5mm on the exhaust valve without having to change the valve seats. So the question is where can I by oversize valves ? UPDATE: I have found these valves for my engine: http://datsunspirit.com/shop/dsi-big-valves/ But the stem length is to long for my use, needs to be original length. Other than that they would have been perfect. and http://www.ferrea.com Wish thay had 1,5mm exh. valves Anyplase else that I should check out ?
