H22A serial number for year

[wavesrcool]

I have an H22A with a 7 digit serial number starting with 303....
Can somebody give me a definative answer on what year it is please.
It is a swap so no good checking the chassis.
Thank you

It is in a 1992 Prelude Si if that has any bearing on it.

And I am pretty sure it is 93 or beyond as I compared manifold chamber gaskets and the ones for a 92 had 4 round holes and the ones for a 93 that fit mine have 4 round holes and 4 slightly rectangular holes.
