I might feel no slight delight if I heard "height" pronounced right.

Interesting that “heighth” is current usage in Ireland.

The second variant of “height” that OED lists is actually “highth”. Some early usages:

1398 TREVISA Barth. De P.R. XVII. xviii. (1495) 613 A shrub that neuer growyth passynge the heyeth and quantyte of two cubytes.

1667 MILTON P.L. VIII. 413 To attaine The highth and depth of thy Eternal wayes.

So it’s archaic at worst.
