Correct. The 20v does not have an oil drain from the head to the block. Oil return direct to sump would be fine provided it was baffled to discourage oil slurping upwards. Otherwise you can drill & tap the block like the 16v & use that original fitting in the block.There is a lug cast on the block for this purpose. I think the factory original cut was about 7.4-7.6. Not exactly sure. I am curious as to why you would want to replace a 20v head with a 16v though.
