Recommended Heat Baffle/Spacer -- Aftermarket or OEM for 1967 Q-Jet?

Hi Guys,

Anybody tried the Mr Gasket http://www.autozone.com/fuel-system...for-rochester-quadrajet-race-only/105114_0_0/

or another make? I am going to replace the Edelbrock that is on my car with a 1967 Q-Jet and I need the metal plate.

Thanks!

 

What intake manifold are you using?
Does the intake flange have the exhaust crossover trough in front of the primary bores?

 

Hi Greg,

OEM intake manifold. Since I don't have a heat baffle at all at this point for the Q-Jet, I am wondering what would be best to go with....

In the future, I plan to port my heads and put in a TA_284-88H cam if that makes any difference. Mild build is all I will be going for in the foreseeable future. Street car and I plan to drive it frequently for 20-25 mile trips one way.

 

Ed,
A 1967 Buick 400/430 intake manifold should use a gasket like #1705:

Originally, there would be a gasket against the intake flange, then a steel block off shim and the carb mounted directly on top of the steel shim.

Now some people prefer to use a 2nd gasket on top of shim.

You must use a steel shim to block off the exhaust gasses.

 

Thank you Greg. That is a big help. Exactly what I needed to know.:TU:

 

Russ Martin also sells the correct size/fit plate and gasket for the '66/'67 Q-Jets.. http://nailheadbuick.com/intake

 

Thanks, I ended up ordering what I needed from Greg G.
