My 55 Belair with a pretty much stock 68 327 SB with a mild hydraulic cam, small valve heads and edlebrock performer series 4 barrel needs intake manifold gaskets due to oil leaks. My question is should I use the gaskets that block of the center port that I assume supplies heat to the carb. I have had some problem starting with engine hot which is pretty good after installing a spacer under carb. I live in Northern Ca. and currently have the heat riser wired open and no problems with cold engine drive ability. Appreciate your input.

I would suggest Fel-Pro 1204 which have stainless steel block-off plates for the exhaust crossover.

I would also suggest using a ¼” bead of RTV on the ends instead of the cheesy rubber gaskets that come with all gasket sets for SBCs, they always squeeze out and cause leaks.

Thanks to you both for your input. I am going to go with blocking off the passage with the fel pro gaskets and seal the ends with RTV.

One further question regarding the installation of the intake gaskets. I will go with the RTV on the ends but I would like to not use any type of gasket shellac on the intake gaskets themselves around any of the fuel or water ports. But of course I am concerned with leaks. In other words might I get some leaks if I install the side gaskets in dry. I would appreciate any opinions on this Thanks

I used a thin bead around both sides of the gaskets around the coolant ports, just a little insurance. Let it set overnight before filling the cooling system.

Fel-Pro 1204 Performance intake manifold gaskets have Printoseal beads of special elastomers around the ports for extra sealing power.

No need for any other sealer around ports.
