ProComp/Speedmaster aluminum heads

We did that at the parts store. We usually had a hot rod engine on display. (Lakewood engine stand) We had a 392 hemi at one time and a short wheel base dragster. I remember, we took that apart, tipped it sideways and walked it in the door. Damn, no cell phones then so no photos of that.

I remember the auto parts stores displaying performance. Unfortunately, all we have are NAPA's, O'reilly's, Advance Auto, and Autozone, none which do that sort of thing.
