I am new at this Buick thing, so bear with me. I met up with an individual that has 6 sets of Brand New Stage II aluminum Heads. He tells me there were only several sets of these type of heads cast. He said they are "Indy Style", they have square exhaust ports and not D shaped. I physically looked at them and they are sweet. 14 head bolts etc. I can get a great deal if I buy all 6 sets, I am wondering what any one knows about these type of heads and if anyone is intereseted in going in with me on the purchase. I can probably get each set for $600.
