Im not sure as to the exact answer to this, put I would speculate that it may refer to front or rear, being that this dictates the exhaust and intake openings.

Could it possibly have something to do with the 88b vs the standard 88?

Where I saw it was when I was looking on ebay for some heads. I hadnt seen it before but since now I am looking at all the ads, I have seen it on several ones.
