oversized or standard size valves??

[dsm1kenobe]

I'm on the fence right now whether or not to do oversized valves. I'm shooting for 450 whp and know that I can do this with a stock 1g head however, I'm not the best tuner in the world so every little bit counts. What are the gains one can achieve with oversized valves vs. standard size ones? Which ones do you guys recommend? Any input is appreciated. Thanks!

100% waste of time unless you have a HUGE turbo, intake and are already making over you're 450whp goals. start thinking over sized valves when you have the above mods and a 60-1 or larger turbo.
