− | When working on the cylinder heads on the older engines (1960-'68) the 1960-'68 heads do not flow well. Replacement 1969-up heads are better, particularly casting numbers D8 and E0 heads, which would come in 1979-'83 model years. These heads have 1.75" intake/1.36" exhaust valve sizes. The exhaust valve seat can be machined to 1.5". The drawback to these heads is the chamber size is 62cc, 1960-'68 heads are 52cc, so compression drops approximately 1 point. There are also Australian cylinder heads with removable intake manifolds, but they are expensive.
