The 601's have 1.84" intake and 1.5" exhausts stock. I know they came on 80-85 HO Camaro's and I've heard 4bbl trucks too (I haven't confirmed the truck).
I have a pair of complete 601's for sale on Ebay with Ferrea 1.94" and 1.6" valves and .550" springs. I also have a pair of untouched 601 castings that have been cleaned and mag'd. Search on Ebay for 'SBC 601' and you'll find the complete heads. Email me if you're interested in the bare castings.
