Head inlet faces
In the picture below you see the right head stripped of the intakes and gaskets, and ready to receive the new gasket set. You'll notice the camshaft oil pipe and new banjo bolts above the inlets if you look carefully. Also notice the cam drive chain over there on the left, and the heater water return pipe running down the length of the valley just below the inlets. The inlets are stuffed with lint-free paper to preclude yours truly from dropping something down into a cylinder.

Intake manifold gaskets/spacers/isolators
Sorry about the strong afternoon light, but I needed a lot of contrast to show you the raised lip on the gaskets. These are the new gaskets being fit-checked and then fastened to the head using an M10 nut on the head studs. Notice the camshaft chain drive crossing the "bridge" from the bottom to the top in the picture. This is also a good shot of the oiling pipe and banjo bolts.

As you can see, there's plenty of room to work once the manifolds are off the engine.
Heater hoses
While I had my intakes out and the camshaft covers off, I decided to replace my 10-year old heater hoses. Here's a good shot of the return hose from the firewall manifold to the return pipe in the engine valley. Notice the other two hoses as well - they go over to the water control valve and auxilliary pump.

That large pipe there over on the left, underneath the heater return pipe is the main water return pipe routing the water from the back of both heads to the water pump. Also, check out the size of those cam lobes - this engine is way overdesigned.
Camshaft covers
Nice shot of the engine with the covers on, just prior to fitting up the intake manifolds. You get a good shot of the water return pipes. Also, check out the left distributor rotor, removed as I replace the spark plugs.

Fitting the manifolds
Here the right intake manifold (located on the LEFT side of the engine, confusing, huh?) after bead blasting it clean of a lot of oil residue and gunk. It's hard to see, but just above the manifold, but below the cam cover are the fuel return pipes. They get screwed down with the same bolts that hold the manifold, so fit checking at this stage become important.

Shows you just how LONG those intake runners are.
Right intake attached
Intake is on and torqued down. Look down the left inlets and you'll see some gold-colored intake valve guides. Yup, your staring directly at the back of the valves. Notice the two fuel rail mounting posts with the gold-colored allen bolts in place? We'll put those on later, since we need access to those bottom bolts on the intake gaskets. It gets tough to gain access to things once we add the left manifold.

Also check out the fuel injector bores to the right of the gasket nuts. Injectors simply press-fit into these holes with oversized O-rings. Also brought up the fuel return hoses for the fuel pressure regulators, and the evaporative purge hoses through the chain bridge and into the valley.
More pictures later. Next installment - the secret trick to fastening the manifold bolts.
