Trans (&engine) install ?'s (anyone near Sacramento willing to come by & help?)
I used to run the Hooker super comp 5116 headers. You have to drop the center link to get them in as one pipe goes around it.
I would have the left header loose hanging in the engine compartment when I dropped the engine in.
Or go from underneath after the engine is installed, but you will have to lift it off of the mounts to get the header wiggled into position.
You can then run the standard starter, but I would get it in position, and get the electrical connections tight and the starter in position before tightening the header all the way, (sometimes you have to juggle the header and starter to get everything in position....
