Maybe overkill but batteries are expensive.

No such thing as overkill when it comes to protecting batteries.

the heat shield provides one other critical feature.

without it its a lot harder to cook sausage rolls and traveller pies on the move.

leave it there, but while its off its worth wrapping the secret hidden heater hose in high density high temp silver backed foam with the silver on the outside.

I haven't seen it done on a cast manifold before, but on after market extractors (which are generally thinner walled) it can significantly reduce their lifespan as the metal gets brittle and crumbly.

I've had mine off for a while, mainly due to that fiddly rear bolt.

I've also recently had the inertia fuel cutoff switch on mine fail intermittently, causing all sorts of grief until I sorted it out. The switch itself had become quite brittle, possibly due to heat. Now, I've not heard of that happening to anyone else, so could be unrelated, but thought it might be worth throwing it out there.

Yes, Plastics appear to have an adverse reaction to heat for some reason Fun test, place an alloy drink bottle of water near the ABS modulator, Go for a quick 25km drive, check bottle temp, should be warm, but not boiling, remove heatshield, retrace 25km drive route, check bottle again,WARNING! will need a glove!

I've spent so much money on this vehicle that I won't be selling it for a while so I'll let you know if I have any problems. Fingers crossed no. Mind you....I do want a VNT and the manifold to suit...

VNT runs find on the standard manifold.

I agree leave the heat shield in place (specially for warming sausage rolls) but also place some glass tube over the oil pressure switch wiring and get rid of the plastic rap.. Or simply install a good oil pressure gauge which will be more useful then the pretty light on the dash..
