dk;
the 289 heads will bolt on to your 302 block with no problems,not sure exactly what valves are in either head,I would get the casting number off the 302 heads and check in with your local ford parts guy and he should be able to tell you the valve size and combustion chamber cc's and then you could check the 289 heads and decide which are better.............My guess is with a little intake and exhaust cleaning up and a good vavle job the 289 heads may produce more power,likely will have a little more compression to boot...........I would take the 289 heads to a machine shop and have them checked out as heads that old could have been modified over the years.............
