This is a clone version of the popular(but expensive) GX160 Hi-Compression 14cc head with valve guides installed and valve seats installed and cut. Great for a stock appearing clone class because it looks like a standard clone head rather than a Honda head. The combustion chamber is 8cc smaller than the standard clone head which gives about a 1 HP boost to a plain stock engine. There is room for additional milling of the gasket surface to get even more compression.
Seats are for standard 196cc Clone Honda GX200 valves(25mm intake and 24mm exhaust)and valve guides are 5.5mm.
The Clone/GX200 Version head will fit the older Harbor Freight Greyhound engine, but you will need a new valve cover and gasket for the Greyhound.
The Hi-Comp head is pictured on the left with a standard 196cc clone head on the right to illustrate the difference in combustion chamber design.
Compatiblity:
Clone 196cc Honda GX160/GX200 engines
Predator Hemi engines (Generation 2). The Gen2 Hemi 27mm intake valve will not work in this head. Head uses 25/24mm valves. A new valve cover will also be required
Note:
The only difference between ADJ-1116 and ADJ-1116P is dowel pin holes.
