Level of difficulty to replace head gasket?
 

I was wondering how much work is required to change out a head gasket. Do you need to remove the engine or could it be done with the engine still in the car? Also, what other parts should i replace while im doing this? Any fancy tools required? So far i have the timing belt, coolant, oil, intake and exhaust manifold gaskets in mind.

You can do it with the engine still in the car. I don't really know details on the process, though.

It took us about 6 to 7 hours with generous eating and clowning around time to change the head gasket on a friend's R. It was cold too b/c we couldn't close the garage. Altho, it's colder now than it was back in January...ironic isn't it?

I'd say give it a little longer for a GS-R b/c it's harder to get the intake manifold off. However, you could opt to remove the head and manifold simultaneously, instead of the manifold first, followed by the head.

If the intake manifold gasket is old, there's a good chance that it'll rip when you remove the intake manifold from the head. Get some permatex gasket remover and a scraper/razor blade to remove the old gasket if it comes down to that.

We didn't remove the timing belt, so we left the acc. belts and crank pulley alone, but I had the crankpulley holder tool waiting just in case. A straight edge with a set of feeler gauges that go down to .002" are also need to check the deck straightness.

should have the head resurfaced
