BASIC W2 BREAKDOWN

There were many variations of the W2 head. And generations to a degree I guess you could say.

A basic break down is the standard 59* and then the 48*. Econo version and the race version. The econo version is just as able in power production as the race head. It has cast in pedestal for the rocker shafts and the race version uses stands. The come in standard spring height for regular length valves and 2 inch spring height for the long valves.

The last run has extra meat around the end lower bolt holes. The prior generation has extra meat as well but not around the end /bottom bolt holes. The first gen has no extra meat on the lower half.

Rocker gear is available from many sources in 1.5 or 1.6 ratio. Mechanical, roller, aluminum or Stainless steel.

The head can make great power and loves large lifts.
