Use a plastic scraper or a brass brush to protect the soft aluminum cases from scoring. Always torque your cylinder head nuts in a star pattern to factory cross-specifications in multiple stages to guarantee an even crush seal across the head gasket.\u003c\/blockquote\u003e\u003chr\u003e\u003cp\u003eCalifornia Proposition 65 Warning\u003c\/p\u003e","brand":"NCY","offers":[{"title":"Default Title","offer_id":67964568535361,"sku":"1100-1033","price":19.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/7785\/2225\/files\/1100-1033_f1493a7c-0b75-49e2-8b7c-712ab64c6912.jpg?v=1792793705","url":"https:\/\/azscooterparts.com\/products\/gasket-set-engine-bore-62mm-genuine-gy6-150cc-ncy-brand","provider":"AZScooterParts","version":"1.0","type":"link"}
