L20b intake and exhaust manifold

[Dataholic]

Alright guys big noob here. I'm changing the head gasket on my L20b and I've taken off the carb and am trying to take off the intake and exhaust manifolds. I'm used to small block chevy's and this is proving to be difficult for my rather large clumsy hands. I've unscrewed 4 bolts from the intake manifold and 4 bolts for the exhaust manifold, and neither seem to be loosening up from the head, can someone help me locate where the other bolts are that need to come out. Thanks for the help.

There are i think 4 more between the intake and exhaust manifolds. the have big washers on them and they hold the intake and exhaust with the same bolt. you will need some extensions and a knuckle to get to them. it is a pain.

Take the head off with the manifolds attached.

Sweet lots of help, while pulling everything apart I noticed three thin plates separating the exhaust manifold, the intake manifold and the carburetor. Do these serve any purpose, I know one holds the air breather in place but I can't see any other reason for them being there. Since it is already cramped in those areas I'm debating leaving them off when I put everything back together.

take a photo. I forgot what the later L20s have on there

Yeah always put up a photo of what you are talking about,it'll get a quicker answer. When taking off the manifolds those little wobbly u-joint things for sockets are your best friend.

Go to Sears and get a 12mm swivel socket with a shallow end. WHen you get that, do a search and find a side view picture of the manifolds. You'll see which ones you are not getting, and then you can get them "by feel". I used the said socket and I THINK a 12 inch extension from the bottom or side, and it turned what seemed a near impossible job into a 5 minute job.
