I would like to find the heat riser for this manifold so the exhaust pipe fits better. Do any other makes work?
Thanks

Have you eliminated the heat riser from your exhaust manifold? Have you taken your Olds to an exhaust shop to see if they can fabricate a new exhaust crossover?

Heat risers are able to be found. Look on ebay for starters, and Fusick.

Unless one does a whole lot of cold weather driving, it really is not needed. Better off to try and locate a heat riser eliminator or simply remove the internal butterfly valve in the current one.

What I have now is the left dual exhaust manifold from a 64 Starfire but don't have the heat riser that has the built in donut. If and when I find one I plan on gutting it and plugging holes.

I presume by left you mean driver side? That is where the heat riser is located on my 1962.

It would seem that someone has made a replacement spacer for this application? At least they should have! I know that spacers are/were available for some mid-fifties Cadillacs.

Hi KQQLKAT,
I sent a PM about the heat riser.
