| − | 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.

They are now being sold by a company by the name of vintage inlines which is the spiritual successor to classic inlines after the company closed its doors due to the death of the owner. The heads are available for the same price classic inlines sold them for. However, the price may vary depending on additional modifications requested such as porting and larger valve sizes. It should also be noted that the head has a different temperature sending unit at the back of the head in the stock location it is a smaller size but is easily found a local auto parts stores. Lastly, the "base model" and also cheapest aluminum head vintage inlines sells has 1.8 inch intake valves and 1.5 inch exhaust valves with a 55 cc camber. The head also comes with aftermarket dual valve springs which claim the following specs closed 110 lbs, open 260 lbs, inst hgt 1.68, duration up to 280 with all other specs being user verified. |
