Review on 🔧 GM Genuine Parts 12622033 Cylinder Head Gasket: Reliable Solution for Engine Performance by Ken Ayo

Less than 500 miles, head gasket leaking. The skins were restored and the soundboard thoroughly cleaned/prepared. Once removed you will find that more than half of the coating has disappeared from the head gaskets unlike any other new or used gaskets I have seen. NO LS9 GASKET AND IT WAS NOT EVEN A GM HEAD GASKET. ONLY 5 LAYERS AND ABSOLUTELY NO TAGS OR PART NUMBERS ON THEM.
