Why?
For the price of doing that swap, you could just have your 2V heads ported and they would flow just as much.

They will bolt to the block. Other than that, nothing will interchange from the ecm/harness to intake and exhaust manifolds. Might look into some Trickflow or Patriot 2V heads.

I think the 3v heads will fit but unsure of the 4v ones - I thought that was a different block (I think that's what was implied on that statement but I'm not sure). By the time you go through all that cost, might be more cost effective to find a newer used engine and ecm, at least cost it out to be sure.

Just some thoughts.
