It’s especially useful for street\/strip vehicles, hot-rodders and anyone experiencing fuel percolation or inconsistent carburetor behavior from underhood heat. If you use aftermarket spacers or require slightly taller fastener length to accommodate installation, the included extended studs simplify setup while the nitrile composite helps the carburetor run more consistently in demanding thermal environments.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the 9266 fit all Edelbrock AVS four-barrel carburetors?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it’s made for Performer and Thunder Series AVS four-barrel carburetors with the matching bolt pattern and center configuration.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Why are extended studs included?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Extended studs provide correct mounting height and simplify installation, especially when adding spacers or insulators.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":48086758162590,"sku":"B00062YBPM","price":54.43,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/edelbrock-9266-front-gasket.jpg?v=1785903707","url":"https:\/\/northtrailauto.ca\/products\/edelbrock-heat-insulator-gasket-0-320-inch-for-performer-thunder-series-avs-nitrile-composite-extended-studs","provider":"North Trail Auto","version":"1.0","type":"link"}
