Technical Tip: Full kits usually contain a cylinder head gasket of nominal (standard) thickness. If the engine block has been decked (plane ground), it is necessary to measure the piston projection and potentially select a gasket with increased thickness (oversized) to avoid piston-to-valve collision. Remember to thoroughly clean the contact surfaces and use new cylinder head bolts.
