My motor was replaced by the dealership a few years ago under warranty. They used a Jasper engine in it. Back then I didn't have internet access to check things out. Now I justed looked up my heads and found out that the heads Jasper put on the long block are the 193 castings. Those are from trucks and TBI cars. The cores they got back from the dealer were the real deal 083 TPI heads. My question is just how much worse are the 193 heads? They're both 64 cc heads with 1.94/1.50 valves, so am I losing that much by having the truck heads? Also, I've since put a supercharger on the car. With it being forced induction, do the flow characteristics really matter all that much?
