Why CNC heads? Because you don't have
the time for hand ported heads! Thats the
truth, and we all know it!  We want BIG horse
power with out any down time! We live in a
fast food/ drive-up generation, and CNC
heads is the way to go. Now you need to pick
what set of CNC heads is best for your
combo and needs. Big ports can give you
higher flow/HP, but if you get them to big you
end up with no air speed so you lose your
torque, A lot of worked went into keeping the
air speed up on the three different intake
ports for the new  CNC heads. Great torque
and max horse power is what you want from
your cylinder heads.  You just can't beat the
new CNC heads!
CNC Heads Come with these features:
* Dual Port type 1 stock style head casting.
* Performance thick extra hard T6 aircraft aluminum castings.
* Fits without modifications to your stock sheet metal.
* 3/4" reach 12mm spark plug holes moved up and over to give more meat to help lessen the
chance of cracks starting between the seats and plug holes like some other heads.
* Thick, solid, chamber blocks to help dissipate heat evenly across the entire combustion
* Extra thick chamber area so if you need to fly-cut for more compression.
* Thick, solid rocker blocks so you can't brake off the rocker studs like the old days.
* 3x angle performance long lasting radius valve job.
* Stainless Steel 40mm, 42mm or 44mm intake valve x  35.5mm or 37mm exhaust valves
* Dual long lasting performance valve springs that ensure extra rpm protection.
* Light weight, real chromoly spring retainers (stronger than stock stamp steel retainers)
* Hardened heat treated valve keepers. (stronger than stock keepers).
* Aluminum-Silicone-Bronze long last valve guides.
* Bore open for 85.5, 87, 88, 90.5, 92 or 94mm
* Complete CNC shaped intake and exhaust ports that do not give up air speed. This means
more torque and better throttle response.
* 3x different intake ports for the three different intake valve sizes! Not just one port fits all!
* Complete CNC shaped combustion chamber built to help with combustion quench.
* Each valve spring is shimmed per your cam and rocker combo for the correct spring
* All exhaust and intake studs are included.
* 1x set of thick Intake gaskets are included
* 1x set of Heavy duty rocker studs are included FREE!!
* Oiled and assembled for true bolt-on out of the box set of performance CNC heads!
