Loosen the front left exhaust manifold screw

[xb-60]

Is it feasible to use heat and a hammer, or just a hammer, to increase the size of the dimple/divet in the pipe so that you can use a ring spanner (closed-end wrench) instead of an open ended spanner?

Cheers,
Glen

I just watched a Roadkill Garage episode where they bashed in the primary pipes with a hammer and claimed it had no effect whatsoever on the performance of the engine.
