From Chilton. Disconnect the negative battery cable. Remove the air inlet hose at the crankcase filter cap. Remove the throttle body inlet hoses. Disconnect the accelerator cable at the throttle body. Remove the cable retracting spring. Remove the cable bracket from the upper intake manifold. Disconnect the fuel inlet line at the fuel rail. Don't kink the line! Remove the upper intake and throttle body as an assembly (see Section 5). Tag and disconnect all vacuum lines attached to the parts in question. Disconnect the inlet pipe from the exhaust manifold. Disconnect the power brake vacuum line, if so equipped. Remove the bolts and nuts attaching the manifolds to the cylinder head. Lift the manifold assemblies from the engine. Remove and discard the gaskets. To separate the manifold, remove the nuts joining the intake and exhaust manifolds. To install: Clean the mating surfaces of the cylinder head and the manifolds. If the intake and exhaust manifolds have been separated, coat the mating surfaces lightly with graphite grease and place the exhaust manifold over the studs on the intake manifold. Install the lockwashers and nuts. Tighten them finger tight. Install a new intake manifold gasket. Coat the mating surfaces lightly with graphite grease. Place the manifold assemblies in position against the cylinder head. Make sure that the gaskets have not become dislodged. Install the attaching nuts and bolts in the proper sequence to 26 ft. lbs. (35 Nm). If the intake and exhaust manifolds were separated, tighten the nuts joining them. Position a new gasket on the muffler inlet pipe and connect the inlet pipe to the exhaust manifold. Connect the crankcase vent hose to the intake manifold inlet tube and position the hose clamp. Connect the power brake vacuum line, if so equipped. Connect the inlet pipe at the exhaust manifold. Connect all vacuum lines. Install the upper intake and throttle body as an assembly (see Section 5). Connect the fuel inlet line at the fuel rail. Install the accelerator cable bracket at the upper intake manifold. Install the cable retracting spring. Connect the accelerator cable at the throttle body. Install the throttle body inlet hoses. Install the air inlet hose at the crankcase filter cap.

I know this isn't manifold gasket.. But I'm getting ready to start with the VALVE COVER gasket on a 1987 F-150 4.9l inline 6. I noticed no one mentioned taking the 2 bolts out of the EGR valve and leaving the line hooked up...
I'm just inquiring because I've seen some videos like that. Where they take the 2 bolts out instead. Is this wrong or am I missing something here? Because I do believe the 2 bolts seem way easier with same results... If someone could help please. Thank you in advance for your time...
