I'm in the process of rebuilding the engine in my 78 620 pickup and I found out that my cylinder head has a little over half a millimeter of warpage. If anyone has an L20b cylinder head they'd be willing to sell and hopefully somewhat close to Eugene Oregon, I'm interested.

I'm attempting to pull the engine in my 78 Datsun 620. Do I need to remove the steering component under the oil pan before I can pull the engine?
