I dont get it……

I got my engine home....(1975 360) pulled the 2 barrel manifold off of it....and then the valve cover......somebody........stuck 318 heads on this 360......3769973 casting number......Why....why would someone do that?......My question is.......the heads are fresh apparently.....nice soft umbrella seals and all....but wont this absolutely kill the performance of the 360? the combustion chambers are 2 to 3 cc smaller......but the flow and valve size is smaller.......should I just run it as is until I can build up another set of heads......or will it even be worth it to run it with these heads on here?
Thanks in advance.......Pat
