Vulcan900 Posted July 13, 2009 Report Share Posted July 13, 2009 If the heads have not been messed with you could try this: http://www.73-87.com/chevy_ids/sbheads.htm But like Gearhead said, if anything was done to the heads its up in the air what the actual numbers will be. This might give you a good place to start though. Good luck Quote Link to comment Share on other sites More sharing options...
HONDATUNER356 Posted July 14, 2009 Author Report Share Posted July 14, 2009 i believe i've tried that site and no luck. it gives all the other info but no cc's. thanks Quote Link to comment Share on other sites More sharing options...
Vulcan900 Posted July 14, 2009 Report Share Posted July 14, 2009 What were the casting numbers? I have a set of double hump heads on my camaro. At one point I found a different site than the one listed that I believe gave all the info including CC. Quote Link to comment Share on other sites More sharing options...
NHRATA Posted July 14, 2009 Report Share Posted July 14, 2009 As rob has said the only true way is to pour them !! Most of the time if they haven't been reworked the valves are sunken so far that what the books say don't much matter but stock 461 were 64 cc Quote Link to comment Share on other sites More sharing options...
