four barrel 318

A-muscle; FYI, The Iron Ram heads are Magnum heads. LX guy, can you provide a link to the site for these heads?

Well, I suppose its a little late for this, but:

Seems like they are a better casting than the stock Magnum head.

Pretty decent performance for the money probably, but you still have to do all the parts swapping (rockers, pushrods, lifters) like you would for the regular Magnum heads.
