:idea: Just wondering if anyone knows anything about these and what they are typically worth. I have a set of aluminum rectangle port BBC heads and aluminum intake with the Winters Foundry snowflake on them. They must be kind of rare. The casting #s say they are from 1969-1971, but thats all I can really find about them. Just hoping for a little more info., thats all. I know it doesn't sound jet boat related, but that's what I have on my Biesemeyer. THANKS
