History Info for the H22 blocks.

The H22 motor fits 1993-2001 Prelude and is also called
the Si Vtec motor. 
The primary applications of the
H engine series were the fourth- and fifth-generation
Honda Prelude and the fifth and sixth generation Honda
Considered a premium choice amongst hot rodders.
The Honda H engine was Honda's high-performance
"big block" engine family from the 1990s and early 2000s.
It is largely derived  from the Honda F engine and shares
many design features.  The F20B, though technically
coded part of the F-series family of engines, was basically
a destroked version of the H22A4 It has also enjoyed some
success as a racing engine, forming the basis of Honda's
Touring car racing engines for many years, and being
installed in lightweight chassis (such as the Honda CRX) for
use in drag racing.
