Also these vortec heads, will they bolt onto my 3970010 block and will my AC, Alt, Power steering just bolt on.

Yes, everything bolts right up. The only difference is the intake manifold and valve covers are different. Vortec intakes and valve covers are readily available. For instance Edlelbrock makes a Vortec version of their Performer RPM and Air Gap intakes.
