"Sorry, L20b/A87 head, square port....I thought all the square port 4 cylinder L series  heads used the same exhaust manifolds. "

For L20B the W58 heads are round port and the exhaust is separate from the intake.

For L20B U67 square port, the exhaust and intake are bolted together.

For L20B A87 square port you could use the above co-joined manifolds or the earlier L16/18 4 into 2 exhaust. A different manifold altogether.
