Hi, i need an alternative for the cometic or sce 4.200, .080 head gasket.
I need this thicker type of gasket. The Sce or Cometic are currently 12-14 weeks away on back-order. //JB

 

Not sure if this will help or what your actual application is but these guys make steel shims to use under head gaskets. I have used them several times in the past to save aluminum heads that need to be milled too much.
