Heat riser insulator block off gaskets?

[snaggletto]

I'm getting ready to install the SOR heat riser insulator block off plate on my '76. I bought 2 of the remflex heat riser gaskets, one for each side of the insulator plate. I'm thinking the stack up will be to thick. Is there a better way?

Use the stock gaskets ... They don't normally leak there on oem carbs

 

[Steamer]

Wouldn't you only need one gasket? Between the exhaust & the plate? There's nothing to seal off between the plate and the intake. Is there?

 

[JohnnyC]

The insulator goes between the intake and carb

@Steamer is correct the only thing up there, on the intake manifold are fins to help absorb heat. Unless what you have headers and installing a fluid heat riser?
Confusing post, Remflex gaskets are usually associated with intake/exhuast manifold gaskets and a heater riser gasket for the bottom of the intake manifold.

Ah my bad I thought he was talking about the insulator 'block'

Sorry for confusion. It is the stainless plate that deflects heat from the intake after the heat control valve is removed. SOR does call it an insulator.

Just wondering how others did theirs.

My Int/Exh combo was rebuilt by the guy who builds MAFs engines. He used two stock gaskets around the block-off plate, and high-temp (orange) Gasket RTV and locked the butterfly flap in the open position - on my '85 FJ60

Has held up great about seven years, now. Be aware, it will take you a bit longer to warm up, but I don't worry about it much since I'm in So. Kalif.

You may run into re-fitment issues using those thicker Remflex gaskets, I would use stock or even just high temp sealant.
