	Identified by the deep rim upstand, about 42mm, and the web on the back face and no hump


	Intially the deep six has a curve in the cutout by the valve. This is known as the “heart” deep six.


	The later deep six doesn’t have this feature and is known as the “non-heart” deep six


	The “flat six” (below)was introduced in March 1971, was fitted to some 1971 model year 2.2 911 and all 2.4 and later 911s. The flat six has the hump so is a tubeless design.
