Sorry, the China rail is the machined part of the block that the intake sits on. Here is a photo from my 5.7 from my ‘95.

There is a layer of RTV that is put on those rails, no gasket. In my photo you can see some of the old RTV.

If you notice a puff of smoke on start up it’s more than likely that your valve seals have gone bad and allowing oil to get past them, burnt, then out the exhaust.

Oh okok thanks for the insight I'll have to add that to the list.
