How to identify Brad heads?

My heads say BAE on the ends, but how can they be identified as to which number they are? I believe they are 5's, but don't know how to tell for sure.

Many thanks to Mr. Reehl for taking time out of his busy schedule to help me identify these heads. Class act.

It turns out to be BAE fuel heads. We won't know which ones until I get the heads off the engine, which will be a couple of weeks or more, but we are closer now anyway. The confusion over Brad 5 heads undoubtedly comes from the rocker system, which says Stage V on them. The heads appear to be dual plug heads, but the holes are spaced farther apart than the dual plug holes in the valve covers. Hmmm. I'm sure somebody here has an explanation for that.

its so the rockers will clear the spark plug tubes..Dave
