GT-40P castings (later model)
3/8" ARP rocker studs
Isky Adjustable Guideplates
1.6:1 FRPP Blue roller rockers
Probe rocker stud girdlem w/ poly-loks
Manley Race Flow 1.84" intake valves
Manley Race Flow 25-degree tuliped 1.46" exhaust valves
Valve guides honed
Custom 5-angle valve job
Gasket matched 1" deep to Felpro 1250/1415 gaskets
Milled to 39-40cc chambers (~13.0:1 with zero deck piston)
Receiver grooves
Appropriate length Crower hardened pushrods
Comp Cams 987-16 double valve springs
Comp Cams titanium 10-degree retainers w/ chromoly locks
Teflon valve stem seals

Full flow numbers available. These are ready to slap on an go Pure Street or Street Warrior racing! I don't have them off the motor yet, but they will be shortly. I'm figuring that the complete head/rocker setup will go for about $1000 (not completely sure yet). I've got probably $3000 invested in these for racing Street Warrior by the time that you figure in all the flow bench testing we've done to maximize flow, runner velocities, swirl, etc. Also will have the matching P50 headers available. These are Jet-Hot coated and have been worked (before coating) to maximize exhaust flow. Also have a set of bare GT-40P castings available, $150 + shipping.

These heads have gone 11.09@122 on my AOD car and made 465hp/424ft-lbs on the engine dyno.
