The group includes inlet valves and exhaust valves, valve guides and valve lifters, a camshaft gear set with thrust flange, plus washers and nuts for installation. The B30A is the carburetor version of the six-cylinder B30 in the 164 series and is considered reliable, but after many miles the valve seats settle and the guides wear oval.

A typical checkpoint during a cylinder-head rebuild is exactly the clearance between the valve stem and guide – too much play lets oil draw past the guide and blue smoke shows up under engine braking. Measure before you regrind the seats.
