Re: how does this help?
In my case it is 60lds off the nose steel head vs aluminum and my combo never came with an aluminum head, but it now has an aftermarket aluminum and steel head.

Re: how does this help?
In 1970 Chevy offered the aluminum head as a factory option on the big blocks. This change is consistent with the other years with FACTORY optional aluminum heads.
I don't know how it helps, but I have 200 pounds of lead for sale if you know anyone interested. |
