2b. I strongly disagree. I'm sure others will as well like Tom, David, SHOshop, the list goes on. 3L valves are the biggest upgrade you can make vs the abysmally small 2.5 valves (the 26mm exhaust valve is pitiful! 
) If you don't do this mod to a 3L your are shooting yourself in the foot! Repeatedly!!!
Not sure about SHOShop, but Tom and DavidZ both had porting done to the intake/exhaust with 3L valves. So did I. I'm saying just fitting 3L valves will not gain anything without porting.
