Oh - it'll raise the compression... like a LOT.

I don't have the numbers committed to memory, but last time I looked the
late heads had combustion chambers in the 40-41 cc range. With a stock
bore/stroke, this'll get you to about 10:1, maybe a tad under.

I'd think of this as a "race piece", but even then, there's some
likelyhood that rules bodies would not allow it. But that's a WAG.
