we found a car at the junk yard with one 487 and one 487x head. we went looking specifically for a set of either one of these. couldyou run a 487 on one side and a 487x on the other in a hobby motor? whats the difference?

I bought a set of heads at a swap meet and one is a 487 and the other a 487x the guy said they both came off of the same car. I put them on my hobby stock and dont see any problems. I dont know if one flows better than the other but they are good enough for my hobby stock.

487x casting heads are lower compression heads with 80cc chambers, 487 casting heads have a 76cc chamber.
