Default Head Gaskets

Hello everyone!
I'm trying to replace head gaskets on a 98 Blazer LT 4.3L 4x4.
It's not my 1st head gasket replacement but it is a 1st for the 4.3L Vortec V6. I'm down to the heads, exhaust manifolds are dis-connected. How do you get the outside 6 bolts out of the heads? Is there some kind of trick I'm missing? Although the exhaust manifolds are dis-connected there still in my way.
I've read plenty of threads on this topic but no says anything about having problems getting these 6 bolts out!
Is it possible that you have to remove the EM's from the engine bay? No one say's anything about doing this either.
Any suggestions will be appreciated!

There's gotta be another way. I really don't want to cut off the bolts that hold the donut gaskets together if I don't have to.
Any other suggestions???

Let me rephrase that! They are dis-connected from the head's but are still attached to the exhaust.

Dis-connected the Y pipe at cadilac converter, need to remove exhaust tube from exhaust manifold to intake and I might be able to pull them back far enough to get to those 6 pesky head bolts.
It started raining on me so I guess I'll try again tomorrow.
