isnt a b16 and b18 head both pr3 and me and my buddy who both have head work done at the same time b18c1 and b16a both have the same model brian crower valves. If you find there are no difference in the measurment of the stock valves i have my b18c1 valves that have been refinnished on the valve face and chanfer and measured and are still in spec for use i just didnt end up using them. Pm me if you find they are the same, i can sell you mine cheap as i have no use for them. And on the brian crower website they pair up the b16a/b18c valves together available in stock size or over size applications so i'm about 99.9% sure they are the same.
