All '69 350s had #5 heads....the W31s has larger 455 valves. Also a hotter cam and flat top pistons. The easiest way to tell without a teardown is check the harmonic dampener. W-31 dampeners were larger than norm...about 7 1/4" tall and 2" deep. Also check for distributor number 1111930 and carburetor number 7029255.

Just curious...why do you think it is a W-31?
