Intake Manifold torque order?
 
I know the torque values but are they in a certain order like the exhaust manifold? I searched but found nothing, I’m just checking before I do something wrong.

Youre right. The manual does not note a sequence like the Exhaust mani

That is correct ^

IMO, since the head and intake manifold are aluminum, I would still torque the fasteners from the inside out. It probably doesn't make a difference, but I feel like the gasket is seated more evenly behind the intake manifold when you torque it like that.

I actually noticed my gasket sagged in middle. So I turned head on side to bolt manifold on. I used a little preassembly lube to hold gasket in place as I tightened bolts from inside out. {thumbup}

And yes, sagging gasket does stick into the flow passage a tiny bit if not pushed up when bolting manifold on.

Sounds like what I do with the exhaust test pipe gaskets under my car. If I don't center them before the first "tightening" turn of the bolts, it will not center itself and risks sticking out into the flow haha.
