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
Accord.  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.

For this M12x1.5 4 cylinder head bolt we do not make a
