340 Stroker: experiences with parts

updated:
I took a look at the 340, mounted on it is an Offenhauser Mainfold, Model 360, and I was able to get hold of a couple of Indy Steel Heads with the 2.02 valves.
Maybe I can incorporate these parts into the project, otherwise I'll sell the parts on
Which cylinder head are you referring to? Is it the LA/X head with LA rocker arm shaft? MA/X with Magnum rockers? Rebuilt stock heads from Indy? Got any pictures?
