stupied question on head removal

[plaaya69]

You should have enough room to get to that screw but since their it two parts to the intake manifold you first need to remove the one where the throttle body sits on and the isc sits on. Once you get that then remove the lower intake manifold and it would make it very easy to get to.
Also you did not need to remove the camshafts you just needed to rotate them maybe once or twice to get to the headbolts.

One more tip, when you remove either bolts that are old or rusty dont apply full force just tap it with your palm a few times and that will break it loose and then you will be able to remove the screw or screws and wont have to worrie that much about breaking them.

Hope thie helps and G/L.
