Do I replace antifezze from block after replacing head ga...

After replacing my head gasket on the 8N, and the radiator was already drained and filled with new antifreeze, should I also drain the antifreeze from the block? I know when the head gasket blew, I was getting
antifreeze in the oil and made it chocolatey, so I replaced the oil and oil filter. But should the block also be drained? I don't think the antifreeze in the block was compromised by any oil getting in there
as much as the oil was compromised by being diluted by antifreeze.

If you have already filled the radiator, it is too late to drain the block. don't worry about it.

Common to get oil in radiator but not possible to get antifreeze in oil unless head or block is busted beyond repair.

Philco. For future reference the anti freeze in the radiator and the block are all intermixed. It is one system. So yes you should have drained both but seeing you have already filled the radiator it will be fine.

I guess a little oil in the radiator, if at all only helps the radiator to not corrode as quickly, I suppose. I was doing a head gasket replacement, and much antifreeze got into oil, so I drained oil, and
installed a new oil filter. Replaced clean antifreeze but never considered the block, but I don't think much if any oil got to the radiator. When I drained the radiator to begin removing the head, I saw no
oil in radiator at all. Thanks for all your replys.
