you need 2 intake valves and 2 exhaust valves. You can get by with stock intake valves its the exhaust valves that are too small.

if you did do oversized exhaust valves, you should see a harder hit off the bottom

You can get them from kibblewhite. Thay are the same valves you would get from web cam. Most only get their intake valves done. Is your head ported? If it isnt you wont notice much from bigger valves.

I think he means lower rpms, as in the sweet spot arriving a little lower. I honestly have never seen anyone do just the intake because the flow restriction is the exhaust. But then again i have not seen everyone.

a harder hit as in the power comes on stronger and quicker in the lower RPMs. sometimes it gets kinda abrupt thus the "hit"
