Look like, makes sense anyway. The Pack C had big exhaust valves I think and a std inlet valve and was mildly ported, still retained the guide bosses in the ports (unlike the D pack heads). The 202 cam was about a 276 degree hydro cam, fast road I think they called it, the next one up was the 203 which they called a clubsport cam. So on the face of it looks right, I've TSR heads here marked up like that. Have a look down the ports, Dave's work is normally very neat and tidy so a fairly good indicator that its a TSR head.
I haven’t bought it yet but I’m looking into it,that’s for your words of advice,you say you have some tsr heads are any of them for sale?
