Simple - years of dyno testing all manner of engine builds with current cam profiles and cylinder head modifications has proven running a higher ratio and more lift is just torturing metal. After all – the valve is only at peak lift effectively for a nano-second. It is what happens between 0.150” and 0.350” lift that is important.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eNo real worthwhile gains are made running to 0.500” valve lift and valve train is put under far less stress.

Circlips holding roller rocker shafts into the end of aluminium rockers have been known to fall out under race conditions resulting in the roller tip collapsing and the obvious consequences, often destroying the head and requiring a full rebuild.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\" align=\"justify\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0727\/3322\/9366\/files\/CCF_000054.pdf?v=1765751242\"\u003e\u003cspan style=\"font-size: 10pt;\"\u003e\u003cspan\u003eAssembly instructions\u003c\/span\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e \u003c\/p\u003e","brand":"Minisport.com.au","offers":[{"title":"Default Title","offer_id":53055393530166,"sku":"SW-CH-1.4-COMP-NA-1","price":1395.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/3322\/9366\/files\/08d8b146-d45d-4af2-8c19-07299490a904.jpg?v=1765323780","url":"https:\/\/minisport.com.au\/products\/mini-moke-swiftune-1-4-ratio-competition-rocker-set-sw-ch-1-4-comp-na-1","provider":"Minisport","version":"1.0","type":"link"}
