I got mine from advance auto, they said they were solid, and 30-40 a piece IIRC.
I took everthing I could off for a good clenaing, and resealed the IC tubes with copper RTV...no problems yet...
I also took off the exhaust manifolds and took a dremel tool to the "ridge" inose the collector (to reduce a little backpressure, hopefully extending the life of head gaskets) whilst I was at it. Removing the manifolds makes the mounts alot easier to get at.
There were no exhaust minifold gaskets on it but I put some on it, and had to take em back off becasue there is gasket material covering up the damn spark plug holes (talk about being pissed)... so use a dremel or tin snips to cut the excess material if you want to use them... I used "spray copper" and the copper rtv to "glue" the gaskets to the manifold before re-installation.
I also did plugs and should have done the wires....
I don't have a vise, so once I got the mounts out, I had to screw the mount brackets to a 2x4 for leverage to get the mounts off of the brackets themselves....
I took off the compressor, power steering pump(need puller, which can be "rented" from autozone) IC and tubes for cleaning too) starter (In think) I also got a good creeper, with reclining headrest (don't know what I've done without it)
It did take longer than I'd expected....prolly 3-4 evenings including a solid saturday, but I was taking my time, especially when I was getting pissed off....to prevent extra damage!
You can do it, just take yer time!
If I can think of anthing else I'll add to this...
