    Could someone give me some info. I want to replace the intake manifold gasket on a 350 5.7 sbc. I've never replaced one before so I'm wondering how do I know which intake gasket to purchase before i disassembly the intake manifold. It's a GM intake with casting numbers 14057055. I'm assuming i need to know what the port size is maybe? Any input would be great.

    Thanks.

    Those are the ones I’ve always used. Like HOGDADDY said, toss the rubber end pieces and use a Hi Temp RTV instead.
