Last weekend I bought what i assume to be an original super Winfield aluminum high compression head. I've tried doing some research to find out what compression it is. I've read 7:1 and 8:1. My head is casting #104 and there is another number next to the casting # that reads 8.25. I'm not sure if that is the compression or not. If some can confirm the compression ratio i would appreciate it. I bought this head for when I build a hot motor for my speedster once I get caught up from building the speedster in the first place.
 
I agree with Rex-A-Lott. It is likely and original as I don't believe the Super's have been replicated. On other Winfields the first numbers of the serial # indicates the compression ratio. After 60-80 years who knows how many times it has been cut.
