So I got some heads that have a slight port/polish to the runners for my build. They were a good price and figured it saves me a few days doing my current ones and I now I can practice more porting/etc on my old ones. They do not come with valves. Can I reuse the valves from my old/current heads or do I buy new ones. If buying new best place to get some. ZZP sells some stainless ones are they any value or worth anything or just run stock. I have new valve seals and 130# springs to go on already. The bowls were not touched either. This will be on a xp set up as well with a double roller.
Thanks!
