I think I am ok. The back of the HEI sticks out 2.75" from the back of the driver side head. The firewall recess is 4" deep. From my pictures and memory I have about 1" between the head and firewall so in theory I should have minimum 1.25", probably more clearance. If not I will get out the porta-power and move the firewall a little bit.
