So many of us say "use search" that in and of itself should be searched upon. You can put them on. It will raise compression if used with the OE B body head gasket. These heads do not flow as well as the iron heads you are removing. You will be saving weight, but losing thermal effciency. But in a nutshell, unless they have been ported, other than weight savings, they are almost counterproductive.
