Should work on all the clone engines including the predators and duromaxes, headgaskets fit but might vary engine to engine. But crankcase gaskets and carb and valve cover gaskets all fit good.

I only needed the head gasket from the selection on the card but it fit very well. The one I replaced was made of a metal material. This one was more like a paper material. But it fit very well and I am very pleased. It was a bargain and I have all the rest of the gaskets if I ever need them. Thank you for providing such a deal.
