Bulkhead heatshield. Anyone done it?

Has anyone added heatsheild to the bulkhead?

Any noticeable improvement?

Would seem good opportunity to fit it whilst the heads / top of the engine is off.

I'm thinking of this bit of the bulkhead.

Just to close this off. Thanks for the above. Decided not to do it in the end. Applied some on the passenger side to cover the [now disused] fresh air vent supply. Layered some off cuts of heat shield on the inside to form a sandwich to block the hole.
