Everything is the same until 2003 headers off a 60s block bolt up to my 96 vortex are you going carburator


Vortec *

not a vortec


On the tbi motors like the 89 the middle 2 intake bolts are at a different angle. So the 89 intake won't bolt to the 73 heads. You can run the 89 heads on it, which I recommend anyway. They will bolt to the block fine. Unless of corse that's one of the reasons your going with a new motor. Then you can just get an adapter for the carbed intake to accept a throttle body.
