I responded to your PM.
You need to get the rest of that stuff. The upper is useless without it, unless you just want to hang it on your garage wall like a trophy.
Get the lower, the fuel rails, and the steel rocker supports and rockers. (You've got to take out the rocker supports anyway, to get the lower. Might as well spring for them. My seller just threw them in.)
It needs to be an 89 or newer. (Yours appears to be correct.)
88s and earlier have bigger coolant ports, and will leak coolant. The earlier ones also have EGR, which that one appears not to.
Edit - Get as much of the sensor wiring as you can. Particularly the TPS connector. It's different from the 4.9.
