They feature high-flow ports and steel alloy intake and exhaust valve seats installed (they do require a competition valve job and bowl blending). The manganese-bronze valve guides are installed with a semi-finished I.D. and the combustion chambers are CNC-machined. Laser-cut guideplates are included, and they accept both tapered seat and gasket-style 14mm spark plugs.","brand":"Ford Racing","offers":[{"title":"Default Title","offer_id":61587501646194,"sku":"FRPM-6049-Z304D","price":1155.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0960\/6643\/7490\/files\/52a8cfe35b1c5711b26ebe40de2a2d4d.jpg?v=1770866071","url":"https:\/\/hypermotive.com\/products\/ford-racing-302-351w-z-head-aluminum-head-bare-63cc","provider":"Hypermotive Performance","version":"1.0","type":"link"}
