Hello, I have a set of ported heads on ebay for sale. These were damaged last year by ups and had a machine shop fix them...they did a excellent job but I need money for my t56 swap.
but Im not giving them away...if they don't sell Ill just keep them.
Ill do 1000 shipped for these.
They are in great shape, you can't even tell anything happened.
I will post pics asap

the ebay auction ended but they are still for sale...
here are some details.

They were ported by CNC cylinder heads and were recently just rebuilt and have been sitting under my bed but decided to do a different project.
They were :
>sand blasted, new guides installed, 2.0/1.57 valves
> complete valve job
> blended bowls
>back cut valves
>milled to 52cc chambers
>new crane double springs, retainers and seats.

Flow numbers are as follows
.100-76-71
.200-133-130
.300-198-157
.400-241-194
.500-274-220
.600-268-221

THose do NOT look cnc at all!! sorry to say...

ALso get some better pics could ya to prove they are cnc and the clarity should be better

transAMdriv3r

they are though, cant tell by the pics...im going to try and borrow a better camera I also have the pics of the heads when I bought them off a member that are better quality ill try and link it.
you can def tell they were cnc ported cause of the lines inside, no human can do that. I was told they were ported by CNC heads by james lee

I still have these guys, all boxed up ready to ship

I have a set of cnc ported heads and I disagree with this statement. The closeup of the intake side of the head clearly shows the machine lines of the cnc bit. They look very much like mine and as was stated, no human could produce uniform lines like that.

I would however question the exhaust flow numbers as they are way off from mine, and in general pretty high for a stock lt1 head, but im not saying its not possible. At any rate, pretty good price if they are bolt and go. What kind of damage was repaired?

mrbadlt1

they are def cnc ported, no arguement there, bump for some very nice heads

I bought them from a member on ls1tech and during shipment the edge was gouged on the intake side, I had a machine shop repair them and ups paid for it.
the new pics are of the head that was damaged.
They were also flowed by that member and he gave me the flow numbers.
But my motor was rebuilt a few years ago and I dont really feel like tearing it apart if nothings wrong so I decided to do a t56 swap instead.

Thank you !
Im being as honest as possible,you cant really tell anything happened but I wanted to let everyone know. they are a nice head. Id have no problem putting them on my car, they were rebuilt and looked over and repaired by a machineshop.

I also agree with the above statments. Clearly you can see the cnc work!

They look like they were CNC ported, but what is all the junk in the ports? Were they sand blasted after they were put together or something?

thats actaully grease, pictures make it look dirty

I am interested in these,however the numbers seem really high for a stock casting head.Not saying its not possible,I have a set of stcok cncd heads,@.600 mine flow 270.3 intake and 198.4 exhaust..Is it possible to post up the actual flow sheet?I am building another motor and looking for a set of ready to go heads.

transAMdriv3r

its a long shot but I can ask the original owner if he still has it. no promises though. just going by what I was told
thanks
if not...ill try to get them flow tested

By the way,what are the casting numbers on these?
