These heads were on my 350 motor when I bought the car. According to the Jeg's catalog, they come in 64cc and 70cc versions. Is there any way to tell which I have?

Thanks!
Jeff

You can tell by the part number, which I believe is stamped in the top of the head. Pull the vavle cover to find it.

OK, there's a raised 6061 cast into the head. A couple of cylinders down, there's a small 8020 stamped into it. Does that help?

6061 would indicate a set of 70c.c. Edelbrock Performer RPM angle plug heads heads.
