273 and 360 interchangeability?

Well, the deal fell through on the longblock :( But a complete 360 was advertised for a way more reasonable price so I'm picking it up this weekend. Ran great when taken out of the car, everything is there except a carburator. The heads are the 3769974 casting and it has a LD340 intake and hydralic cam of some sort.

I will take it apart during the winter. Weird, 360's that I can afford never show up here, and now all of a sudden two did. I'm really excited. With this build I want to do a reliable, spirited, street engine, focusing on torque. I already have a 8 3/4 rear end with 3.73 gearing and a 10" 3000 stall converter. A good start! Can these heads meet my goal of a good street torque with the right cam? Compression would be on the lower side I suspect with these heads? Maybe something like the XE268H grind?
