Predator HEMI cylinder head 28.5 / 28 BIG VALVE SEATS /POTRED /GUIDES -$100
Predator 212 HEMI cylinder head /WELDED/ 28.5/28 BIG VALVE SEATS /POTRED /BRONZE GUIDES. BEST HEMI HEAD ON THE MARKET. This is a Pauls karts cylinder head : as seen on you tube. #1 This Head is the ultimate stock appearing head for sale in America! Hemi head new casting. Welded chamber for higher compression and increased cylinder fill. Shaped chamber (radius cut on mill with custom trade mark radius bowl cutter). Chamber shape allows high velocity around valve for increased cylinder fill. Increasing cylinder fill allows for increased torque and fuel air mix quality and gets air deeper down into cylinder. 28.5 mm chrome molly intake seat installed to allow more intake Cfm and air/ fuel mix to enter the engine. 28mm exhaust seat installed to allow better exhaust gas flow valve seat. Seats installed , stock seats removed , seat counterbore milled to accept bigger seat , seats pressed in. Stage 3+ porting done by Paul himself from at Pauls karts on you tube… Professionally shaped from years on the flow bench that I personally own and operate daily and proven to produce better Cfm / higher port velocity and more power than other cylinder heads… (only have 1 stage, CORRECT, this head has the best of everything I offer). Bronze guides installed harder than most guides on the market have made custom for Pauls karts only. Bronze guides allow for closer valve stem clearances which allow better valve controls especially in higher rpm range. Valve guides reamed to exacting sizes for tighter clearances and better valve train stability.. Valve guides honed to set final clearance of. 0012 (thats 1.2 thousands).. The hone cross hatch allows for oil control and increased valve / guide life and cooler valve temps. 3-5 angle valve job cut into the valve seats most companies dont even have the ability to do these cuts or dont choose to because of the extensive cost in tooling and time spent on setting up the valve seats and dialing in the angles… The widths of the cuts and angles used produce extremely laminar flow thru and around the seat.. 1/4 before to 1/4 after the seat is the most important part of the entire engine.. This area depicts how much air you can flow and Cfm has a direct correlation to HP… Valve spring pockets cut to accept larger spring diameter and dual springs if needed.. Hemi heads come with recessed spring pockets that only allow you to run up to a 26lb spring.. This modification of cutting the spring pockets as showed in the picture above allows for increased spring size and higher rpm capabilities which equals more HP.. Horse power is made by increasing cylinder fill at higher RPM S.. Polished chamber for increased thermal reflectivity and smoother flow and helps keep detonation down.. Also keeps carbon from building up and sticking causing hot spots and detonation. Machining causes sharp edges and points in chamber – these are hand rolled and smoothed to increase flow. Polished exhaust port for increased thermal activity and smoother more laminar flow and keeps away carbon build up.. Hemi heads come with shaft mount rocker bosses built into the casting and is one of the best rocker mounts in the industry.. This helps to stabilize valve train and fight off power robbing harmonics created from the engine thru the valve train. This head is made by Pauls karts.. A front runner in the mini bike and go kart industry.. Pauls karts keeps up with all the latest trends in the mini bike / karting / automotive and motorcycle industry and uses this technology and thinking to create more power from these engines.. If your looking for the competitive edge you have found it.. Because each product is made by hand please be patient during high volume times of year.. 3-7 days to create a head depending on specific modifications. Thank you for your support..
