here is the deal bought a set of heads off of a guy on here and a machine shop said water got to them and they were pitted, at least on the intake valves. he suggested buying new intake valves, i am using a set of 317 casting heads staying stock size. would zo6 valves be good or manleys. not sure on what to do or where to buy. i heard the zo6 valves were sodium filled any truth to this? main question is which ones and where to buy?

thanks

 

The Na filled valves are much lighter but they're about $42-$48 EACH.

So multiply that by 16 x $42 = $672 in valves.

However, TEA did have sets of used sets for sale for about $150 I believe. You could call them up and ask.

The Manley should do just fine. I wouldn't have a problem running them.
