Well the spare head I got to keep the down time of Jar-Jar down had both valves bent. So after alot of ho-humming trying to decide on what to replace them with I decided to go with Black Diamonds. First impression, so far is there are no sharp edges to heat up that could cause pre-ignition or easy biuld up of carbon. Ive only gotten the exhaust valve so far, but Id imagine the +1 intake will look pretty much the same. I can also feel a weight difference, but dont have a small scale to get exact specs. All in all Im impressed with them so far, Ill ad to this as things go.
Heres some comparison pics for you guys
