    Default manifold restrictor inserts

    I got these with a fel pro gasket kit i bought way back... didnt use half the stuff in the gasket set... One thing it has is a package that says manifold restrictor inserts, they are probably 1"x1" and thin metal and have a hole in them... What are these for? I'm guessing to restrict the cooling system up into the intake manifold?

    To block exaust crossover in the intake, I use a piece of stainless, block it completly. In the center of the intake right?

    Ahh, you know your probably right. They look like they would fit perfect here... My restrictors have a hole in them.. guess thats why they are called restrictor inserts and not blockoff inserts

    You don't need them Shaun, your T Ram doesn't have a cross over passage. If you like, you can install them, put a little silicone in the restrictor hole. Might keep your T Ram from getting carbon on it where it lines up with the cross over ports.

    Yep, exactly what they are for. Pretty much stock aplication only for under-carb manifold heat, for emmissions and cold weather driveability.
    Very few aftermarket manifolds even have the crossover passage.

    With tuned, open exhaust, the amount of exhaust crossing over would be minimal anyway. Even a stocker needs some sort of restriction to force exhaust through the intake, like the old heat riser, spring loaded, flapper just before the head pipe connection....Damn I feel old knowing that..........Ray
