stupied question on head removal

[suprabahamut]

I have got all the right tools now the hex sockets and got most of the parts off the engine like the cam shafts, valve covers, exhast manifold, and other parts. All I need is the intake mainifold off, the bolts are jamed on there and some of them have been rounded off. so my stupied question is can you just loosen the head bolts and take them all out, to where the head is ready to come off and pull the head with the intake mainifold off togheter and work on the manifold where I have more room and can get some chananal locks on the rounded off bolts is this possible
