i recently replaced all 8 exhaust valves on my b18c1, the motor is all stock .
i put the head back on, adjusted the valves now i noticed that the car idles about 200-300 rpm lower than before, and also i feel like i lost some hp/tq in both the low and top end, the timing off the Distb. was at 15 degrees, anybody have any clue or tips to what i should check and or try
please and thanks to everyone
