The blue flame head was first introduced on the 1935 engines, the spark plugs angle in instead of the 33-34 straight in. All the six's up to the 216 cu.in. in 1937 had 3 main bearings. Stove bolts are the slotted round headed 1/4 -20 bolts that hold just about all the engine sheet metal and other components on the early Chevy's. All the four wheel mechanical brakes are better and safer (if the soft woven lining is used and brakes properly adjusted) than any of the hydraulic brakes up until the dual master cylinder power and air brakes were first used.
