{"product_id":"clone-high-comp-head","title":"Clone high comp head NON-HEMI","description":"\u003cp\u003eHi-Compression 14cc head with 5.5mm valve guides and valve seats installed to accept 25\/24mm valves. Great for a stock appearing class because it looks like a standard clone head. The combustion chamber is 8cc smaller than the standard clone head which gives you a nice boost to compression. There is room for additional milling of the gasket surface to get even more compression and the ports have a little extra meat for porting mild to wild. The dowel pin holes are the only difference between the two options.\u003c\/p\u003e\n\u003cp\u003eFits the Non Hemi Predator engine Gen 1 \u0026amp; Gen 3. The Gen3 RTC 27\/25mm valves will not work in this head because they have a 5mm guide. This head uses 5.5mm stems. The old style Gen1 25\/24mm valves will work. \u003c\/p\u003e","brand":"ARC","offers":[{"title":"Default Title","offer_id":42447420653652,"sku":"DJ-1116P","price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0582\/0914\/0820\/files\/20250917_122444.jpg?v=1758136155","url":"https:\/\/gnarlycustoms.com\/products\/clone-high-comp-head","provider":"Gnarly Customs","version":"1.0","type":"link"}
