Swampfire wins. He's immune to all heat and fire attacks, which is all Heatblast can do. And even if Heatblast damages him he can regenerate. While there's heaps of abilities that Swampfire has that Heatblast is vulnerable to, like vine incapacitation, sleeping powder, or just a plain super strength punch.
