how to make 360 more torque

it doesn't have heads on right now. the ones he gave me are brand new don't know what brand tho. As for Serviceability what do you mean by that?? What parts should i replace

By serviceable, I mean: pressure check good, good sealing valves, correctly chosen and set up springs for your cam, square surfaces, good threads, etc...

You might not have to replace anything-I was just curious where you are with the heads.

I guess I read over the part where it didn't have heads. So, he gave you a set of heads? Are they aftermarket or refurbed stock? Do you see any casting numbers? Can you post up a pic? I'm sure someone on here could ID whatever you post.
