Re: did 57s use a heat riser on all engines??
Darryl, I'm pretty sure only on the carburetted engines used the heat riser as they have provision for the exhaust crossover in the intake manifold.
Fuel Injected engines had no crossover in the inlet manifold so they would have used the exhaust spacer in place of the heat riser.
If you look in your 1957 AIM under Option RPO 579 it may show the spacer part#. I don;t have my AIM handy.

Re: did 57s use a heat riser on all engines??
All '57 to '65 FI engines just had a spacer in place of the heat riser used on carbureted engines. A heat riser is not necessary on port injection engines because the manifold is not "wet".
