Re: Need Cylinder Head, '34 8. What Yrs would be Interchangable ?

According to Hollander's Interchange, 34-38 320 engine heads interchange. That would be 1100-1-2, 1200-1-2, 1400-1-2, 1500-1-2, and 1603-4-5. A notable appearance difference is the provision for a cylinder head thermostat on the later heads which will require a little creativity for the upper radiator hose fitment.

Though Hollanders specifically excludes earlier heads, I suspect they are incorrect and believe a 1933 1001 head will also interchange and would have the same water outlet neck as the 1100-1-2. I believe my 1100 has a 1933 head, I'll check and post the casting number shortly.

PS - no casting number on the head, but the later head on my spare 1934 Eight engine has casting #242511.

And note that with the later heads you'll be going from 14mm to 10mm spark plugs.
