valves question I'm planning to go Procharged and I have two set of heads; one a 243 with sodium filled valves and the other is a 317 with regular valves. I'm planning to run just 8 pounds of boost. My question is: Which head I should use and if the answer is the 317, being that I have the two valves sets option, should I use my sodium filled valves instead of the regular valves or leave the regular ones? SOME LIGHT ON THIS PLEASE. Thanks.

317s have a larger combustion chamber correct? If you wanted to lower your compression a little i'd go with the 317s especially if you're running the stock bottom end. As far as valves go i say the lighter the better. I don't really know what valves are in the 317s but but in my 01 Z06 i spun the ET Ls6 heads to 7300 rpm daily.
