360 with 4.04 pistons?

Dang, you all seem to know what you're talking about. The insight is much appreciated! As luck would have it in my search for heads I came across a 72 duster with a 360 in it. No way would I put that on a dirt track but I'm thinking she will make a nice little street rod! That being the case I don't think it's worth my trouble to go all out for the few extra cubes. Regardless, thanks to everyone for their swift and knowledgeable input!
