I recently posted a question about the roush 180cc head. Through diligent research, (i.e. web browsing and old stack of MM&FF sniffing) i cam across a good head comparison series. I am simply posting this so it will come up if anyone needs it at a later time. The World Product Roush windsor Jr head overall ranked only slightly better than the GT40P head, but still was an improvement over the stock E7 head(how could it not?) If anyone wants to look up information involving 180cc intake port heads or smaller it can be sourced for flow numbers in the august 03 issue of MM&FF. For sample dyno numbers check out Sep 03. I have also decided to forgo the entire motor and instead simply purchase some Edelbrock's. In the long run maybe this won't prove to be as smart, but right now this seems like the right choice, unless someone else is interested in picking up these JR cast heads from me.
Thanks guys
