If your just doing the heads and not porting them then just stick with the stock valves. But if your stock heads aren't cracked then its not really worth the trouble. I do recommend having the magnafluxed, a 3 angle valve job and new seals, springs, and retainers. and you can have the machine shop mill the valve guide to allow for .600 lift. And paint them while they are off.

I have brand new seals, locks and retainers if you haven't bought them already.

I recommend crow cam 105s with the xp can, comp cam 105s had a bad batch and springs were breaking. Hell since your going with the double roller then you could do 130s but if you don't plan to change your stock shift points then its worth it.
