HEMI HEAD & CAM

Hemi Head & Cam Upgrade

Leveraging relationships with some of the biggest names in the aftermarket automotive industry, HPF delivers a premium Head & Cam solution for the Gen111 Hemi engine so if power is what your chasing, then look no further. 

We start by talking to you the customer to establish what sort of result you are looking for and then based on that discussion we advise you on our camshaft recommendation. Once the plan is set, we move on to performing a baseline dyno run to establish what your car makes on the HPF dyno, then the cooling system gets flushed and the top of the engine is removed. 

Your heads are then sent off to Higgins Race Heads for CNC porting and the old cam and lifters are removed. The surfaces are cleaned and cam bearing inspected. We continue by installing the BTR BTR’s camshafts line up, BTR Phaser limiter / lock systems, and valve springs. 

We offer a number of different sized camshafts for the Hemi including BTR’s renowned Truck Norris for the 5.7L Ram, Jeep GC & 300c, which offers an additional 1500rpm of powerband and a nice chunky idle, too a boosted Trackhawk camshaft that offers a very tough idle and the extra power to match – choose you’re poison. 

Supporting the BTR components are high quality non-MDS hydraulic lifters, heavy duty Crow Cams pushrods, quality gaskets and lubricants. Once the engine is all put back together, the tune commences on the dyno. Performed over 4-5 days and supplied back to you with a before and after dyno graph your new Gen111 Hemi will be grumpy to meet you!

• CNC ported cylinder heads - The late model Hemi engines benefit from accurate CNC cylinder head porting. We use Higgins Race Heads out of Dandenong Victoria exclusively for all of our cylinder head porting requirements. CNC porting is the computer-controlled reproduction of a port design machined into your cylinder head casting, this ensures each intake and exhaust port not only flows and has the highest velocity as possible but also flows exactly the same as the port next to it. Higgins Race Heads thoroughly recondition the cylinder head including decking flat the surface, CNC combustion chamber machining and valve seat angles, tip and reface the valves, new valve stem seals and fitting the HPF supplied Brian Tooley Racing valve springs.
