To start, I have a 1994 z32 tt and I'm replacing the head gaskets with the engine in the car. Now before everyone says to just pull the motor, I don't have the space or a lift to pull the motor. If I could, I'd pull it. So back to my issue, I have the upper and lower intake pulled, timing belt, water pump, ext, off the front if the motor, the 8 head bolts, the two 10mm bolts, and the down pipes unbolted, but the heads still will not budge. Do I have to remove the power steering pump too, or what am I missing?

Exhaust manifolds? you didn't say you removed them and they are obviously attached to the heads and the turbo's. That's the reason I'd find a hoist and get the engine out, they are dang near impossible to remove in the car. PS pump is only on passenger side and IIRC is bolted to the head, you'll need to remove the pump from the bracket but the bracket can stay on the head... IIRC.

I've read through the service manual on it and it's not very detailed, but that's what I've been going off of. As for the exhaust manifold and turbos , I decided to keep them connected to the head and pull the heads with them still connected. I unbolted the downpipe from the rest of the exhaust too. I haven't had much time lately to work on my it, but tonight I plan to work on my z well into tomorrow morning.

ugh, I'm not sure that you can pull them all together. Removing the oil feed lines for each turbo from the source is far easier but then you have a bunch of lines hanging off the turbo, same for the coolant, the turbo oil drain pipes as well. the turbo's tuck in under the block, I really don't think you can get it out as an assembly, especially on the drivers side. If you do manage it it's gonna be a lot more difficult than yanking the engine. I strongly suggest you hit craigslist and start offering people $50 for their used hoist, someone wants it out fo the way.
