I'm going to give an alternate opinion because, well I've built a lot of combos which I think is more important than keyboard theory.

I think 180 heads are nice for 305s. Do any of the posters here have any timeslips with the 180 heads on *their own combo* ?? I have not seen any, but I could be wrong.

A 195cc head is about the smallest I go with for performance applications. Some of the best combos I've built were with 200cc sportsman heads. As jsup pointed out, the TFS heads are a good deal too. I'm referring to the 195cc 23* heads. They flow 254/185 CFM, have fast burn chambers, etc.

For a cam, you really cannot beat the comp 503, or similar grinds. I've tried numerous cams from as small as edelbrock 1002 to comp 306s and I just keep going back to that 503 cam. (224/230). The thing just makes tons of usable power from 2000 - 6000 RPM, which is what you want for a street car - yet still builds enough torque to keep the car rolling in 6th gear on the highway.

As far as intakes go, I'd match it with a miniram 1205, a victor EFI with a dog house, converted LT1, or maybe even an HSR. Without any disrespect to folks trying to sell super rams (because we know they are WORTH a ton of money) I think the manifold is an absolute turd and only useful if you live in California and need the EGR/carb approval. Considering I've built my own intakes, done back to back testing with numerous intakes, and have been the moderator of the 'alternative port EFI board' over here: http://www.thirdgen.org/techboard/alternative-port-efi-intakes/ well then I think my credentials are ok..
