Gen 3 Hemi cylinder head porting

We use a SF-600 Flow bench to test all of our cylinder heads. The heads are all ported and blended by hand.

Sending in heads is a MUST as we do NOT keep a inventory of cores.

If wanting aftermarket valves we have a in-house option to run a 2.100" Intake valve and 1.625" exhaust valve for the 5.7L Eagle heads. It is a $1300 upcharge for the larger valves as it requires custom springs, locks and retainers. Springs are .700" Lift capapble and the retainers and locks are steel but can be upgraded to Titanium.

ALL prices include a valve job and cleaning of the heads. IF the head is severly dirty (requiring 2 or more cleanings) a $50 surcharge will occur.

Dyno Picture is a 392" Gen 3 Hemi with FRP Tomahawk 2.0 Camshaft and our Ported Apache Heads (Stock Valves). Picked up 140.5 WHP and 95.4 WTQ. Car was Dyno'd @ Defier Performance in Cary, Illinois.
