Up for sale is my P72 Killer B CNC ported head done by Jason at Performance CNC. The head has been freshly decked and hot tanked clean. The head has Ferrea Standard sized valve guides, I have brand new Ferrea Valve Stem Seals in the bag, and included is Ferrea Comp Plus Intake and Exhaust valves standard size.
The head comes with the matching cam caps, but does not come with valve spring or retainers. I figured that whoever is going to run a head like this would not want to run it with stock valve springs or retainers and I am keeping mine since they are 110lb springs that will be used with my web pro cams.
I am paypal verified and am asking 1100 shipped. I think this is a pretty nice deal since most stock heads are around 400 to 500 bucks plus the CNC Port work was $1100 alone not to mention the valves, valve stem seals and guides this is a pretty smoking deal.
Did this came flowbenched?
What do we know about the flow.
Im interested
When it got done it came with a flowbench sheet but I don't have it anymore, from what I remembered it flowed like 298 CFM through it. For me it was a great flowing head, for example I've made 960whp on a 62mm turbo where others have trouble making 850whp on the same turbo. Now obviously there can be many factors that play it that but it has done me well. My car ran an 8.8 with that head on a stock ported Victor X with Pro 1 cams on a 68mm turbo LOL.
The only reason I am selling the head at this point is because of the power my car is going to make, for example I have Ferrea Valve Guides which have handled 1100 wheel horsepower but now that I am shooting for 1300whp I am going to run Manganese Bronze Valve Guides which will handle more heat along with A3 Beryllium Exhaust Seats again to handle more heat. I'm not going to give all the secrets out but the valves are not going to be your standard ones so the easiest thing for me to do at this point is start with a stock head.
This is a great head and is being sold for a great deal in my opinion, anyone who invests in some good valve seats, springs and retainers will have a very solid head.
You can call or email them as well for flow numbers, like I said I had a sheet when it got done but have no idea where it is now LOL. Last time I talked with them the guy I dealt with was Jason.
Dropping the price $900 buyer pays shipping which is around $60 bucks to most of the US.
is the head milled? And if it is hiw much? Will the head need togo to the machine shop or is it ready to installed? I know you mention you keeping your springs.

Yes it was milled .020” and it doesn’t need to go to the machine shop but needs to be assembled so if you know how to assemble a head then no problem.

Understood, are the valve locks included and like how many passes with the valve guides and valves( trying to figure out how much life is still in them)
Sorry to bother but I have a quick question, what carriers charge 60 bucks for shipping and how do you prepare the head to get shipped?
UPS, I sent a head from AZ to 4piston with 1000 dollars insurance for 60 bucks and the box I got lucky my buddies shop had just received a head from Endyne so there was a box with all the foam fitted pieces to support the head so I got lucky.
