It will bolt up but there's a port mismatch not ideal but nothing to overly worry about. Don't know the rest of your combo but I'm guess but I'm sure an idle - 5500 manifold would be a better match.
Everything is port-matched was just worried about all the other holes really.
The combo should work, I was definitely torn on the intake selection. Have zero-decked KB167 pistons, comp cams XE262 cam, 1.88/1.60 valves and will be running a high stall torque converter with a 3.73 gear ratio. My foot also might as well be made out of lead so that was the deciding factor.
Without the second opening in the back I was having a hard time visualizing how the water would flow through the heads if the intake had just that one opening.
