So my buddy bought a 70 Challenger 340 back in the spring & the car had a running 318 in it, but the original 340 came with it. He just found out the heads are no good. So what would be y'alls advice on what to do heads-wise? Look for a good original set, or aftermarket? If aftermarket, which heads?

Thanks for the advice.
