Air intake heat shielding

[coupe deville]

Came upon this M104 head refurb http://www.flickr.com/photos/lop124028/sets/72157605115286959/ and noticed the heat shielding on the air intake. Is it worth doing, would it make a noticeable difference ?

Heat shielding would indeed help, I doubt you would notice it though.

The 2 best ideas for stopping heat build up on the inlet were a carbon fibre inlet manifold, after a full load pull on the dyno the guy just put his hand on the inlet and it was quite cool.

The other was what I believe to be a resin spacer, this stopped the heat transfer from the cylinder head.

Personally I wouldn't bother unless I was going for big power.
