Loosen the front left exhaust manifold screw

When you reinstall the side pipes, be sure to use a little teflon thread sealant so you're less likely to have the same problem next time. Also, the header bolt shown in your picture uses a 7/16" wrench. Switch to bolts that have a 3/8" head (ARP makes them). That will allow you to use a box end wrench rather than an open end wrench.

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,

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.

I can't check my car because it's in a bag for winter storage but I'm pretty sure I have the 3/8" ARP bolts and don't have a problem getting a box end wrench on any of them, so this is good advice.
