No it's raw fuel coming out between the head and the exhaust manifold. But it runs great, I'm not saying 400 hp great but it runs pretty dang good. Just like when it was coming out of the # 2 cylinder which was the reason the motor had to be pulled to get the heads redone. But back then only the #2 was leaking much worse, but now I have multiple cylinders seeping fuel and running down the exhaust manifolds and dripping from where the exhaust manifolds connect to the cross over pipe.
