It will, but not nearly as much, at least not nearly as quickly.  Instead
of the manifold getting radiant heat seeping through the entire gasket
surface PLUS conductive heat from the bolts, it only absorbs heat through
the surface area of the bolts (a few square inches at MOST).  The manifold
is aluminum, which absorbs heat quickly, and the bolts are some kind of
steel, which doesn't transmit *quite* as quickly.

On a roadrace car, this is something to seriously consider, because heat
soak is a big issue.  For a bracket racer with 30+ minutes of cooldown
between run, not so much.  I doubt an autocrosser would notice any
difference at all.  But I'm a monkey.
