The camel hump heads were reserved for the higher performance Small Block Chevy engines. This particular head has the larger 2.02 inch intake and 1.60 inch exhaust valves which were used on the Z/28 302 engines, LT-1 350 engines, and other solid lifter applications. This head has a casting date of H 21 9 which decodes as August 21st, 1969. This is a real deal factory 2.02/1.60 valved camel hump head. This is a very nice original head.It was recently removed from a good running Z/28 302 engine that came out of a hot rod. The other head was casting number 3991492 which is the direct replacement for this head so I decided to sell them separately. The "492" camel back head can be found in my other listings. This head is in very good condition as shown.
It is complete with valves, springs, retainers, screw in rocker studs, and guide plates as shown. The intake and exhaust ports are completely stock with no porting or modifications. The only flaw I see if a helicoil in one intake thread that should be redone. This is a very hard to find factory high performance camel hump head.
This is your chance to own the original 2.02/1.60 3927186 head you have been dreaming about at a GREAT PRICE! Check out my other listings for more rare and hard to find parts including the 3991492 head that was being used with this head.
