Please mention this p/n 31307 dowel when ordering and we will include 2 with the kit.

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.
