None of the bolts were broken, which i hear is usually the problem, but i noticed when i was getting them off that some were f@#king tight and others not so. This in itself would cause problems.

IIRC the head bolts are torque to yields and require a special torque wrench.
I used a set of 2nd hand TTQ's from a 5.0 when I replaced the heads on my old Mustang a few years back, at the time I didn't know they where TTY's and tried torquing them the normal way, I could never get them to torque correctly and ended up blowing a head gasket, ended up replacing the bolts with the normal type, never had a problem after that.
BTW - TTY bolts are generally only good for 2 torquing sessions, one from the factory and 1 after.
