BTW, forceofhabit, welcome aboard. Sorry to b!tch about your first post, but those manifolds are bad news. Float test the 1 set you have. (Throw off boat and see if they float.) Now, there are a bunch of Chicago area guys on here. Mild Thunder and Mike Tkach among them. Season is about done. You need 2 sets of exhausts. The gil mercruiser are pretty good and will support more than those 420's need. 2k will get you 4 new manifolds, and the risers can be found used with a little patience and ebay-craigslist surfing. There may even be a setup you can use those tails on, but I doubt it.
