Stating that \"My own flow bench testing and computer modelling has indicated that as much as 180 horsepower is on\". \"At first sight the use of three exhausts instead of four might seem like a strike against the 7-port configuration. In practice this appears to most certainly not be the case. Since the centre ports exhaust at 360 degree intervals there is no sharing of exhaust time.... and results to date indicate that the shared centre port of a 7-port head actually seems to work slightly better than having a separate exhaust port per cylinder.\" \"The 7-port head configuration has the advantage of having the same valve sequence as a conventional five porter and therefore can successfully use much the same in the way of camshafts. Also.... a conventional LCB exhaust system can be used.\"\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Minisport.com.au","offers":[{"title":"Default Title","offer_id":44491727372598,"sku":"ALLOY-HEAD-7-PORT","price":5995.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/3322\/9366\/products\/2129_133d07ef-b812-4efa-9e24-42634e52493b.jpg?v=1677154261","url":"https:\/\/minisport.com.au\/products\/mini-moke-1275-7-port-cross-flow-head-kit-c-w-fitting-kit","provider":"Minisport","version":"1.0","type":"link"}
