For me, the front of the car with the engine removed was high enough. By getting the back end way up in the air, the engine will slip in easier and need less boom, therefore less bending. Slide the Hooker Header in through the radiator opening with engine about 3-4" off the motor mounts. Once the headers were on, I bolted the engine block mounts into place and dropped the engine in place. I did trim the drivers side shock tower reinforcing about 1/8" when I prepared the engine compartment for paint. Just enough clearance to prevent front header bolt interference.
