Re: [Amc-list] Tom Jenning's 304 valve swap

[Wrambler242@xxxxxxxxxxx]

I looked at valves when I was thinking about doing the gen I heads and you can get a surprising variety of chevy stemmed valves in many lengths and head diameters. Even though they may not have been a "stock" size there is a lot to choose from!
   someday, maybe I'll even build those gen I heads...
