I picked up a set of stock 243 heads, and I was disassembling/cleaning them to go on my car. They came off a newer avalanche with ~45k miles, so they have the heavier valves which have normal corrosion build up on them.

Is it worth replacing the valves or going with something lighter while I have everything disassembled? Where's a good place to find replacement or performance valves for stock heads?
