Let's talk 318/349/390 strokers.

Rat patrol, let me try to re-word the question (english in not my native language, so it's natural that sometimes I cannot be clear on what I'm tryin to say :D )

What kind of headers and head gaskets i have to use to suit the size of combustion chambers displayed in the site?

Good to know about Campbell Enterprises... Do you people know other companies that offer stroker kits like CE ones?

Thank you!
