Just had my Patriot Stage 2 59cc's flowed
I bought a used set of Patriot Stage 2 59 cc off this board a couple weeks ago and had them cleaned up a bit. I had Chapman Racing do a valve job, replace the springs and redo the valve guides. Once they were all cleaned up I had a friend of mine that works there put them on a flow bench. His best number was 278 cfm on the intake side at .700 lift. A little below Patriots claim of 300+ but still good for the money I guess...

That's nice if you're running a .700 lift cam. What's the flow numbers at .200, .300, .400, and .500" lift? That's what's gonna tell the real story.

yeah, get the flow numbers at all lifts. the lower lifts are really important because the valve is open at non-peak positions twice in an intake or exhaust cycle. I also have a set of patriot 59cc ls6 heads, and i like them a lot. especially for the money. honestly, youll know its worth it once you hit the gas. i put down 405 at the tires with my mods + or - some pieces. ive bought so much for this car. sorry for the long post, just haven;t been on in a few monthes.

bore, bench, and valve sizing?
at any rate, those woulnt be considered PP heads per say as they have had a new valve job by an outside vendor. did he flow the heads prior to working on them? you cant compare your numbers to what PP advertised because they are no longer the way they left the PP facility.
the set i had testest almost over a year ago was in line with what PP advertises, taking bench and port variance into account.

You can basically get 278 with an aftermarket backcut valve and a well blended 2.02 radius valve job. Something is up with your heads. Did he happen to flow at 25" or something

wow. 278 at .700. what completely worthless numbers and crappy to boot. do you realize your cam lifts to .581? you shouldn't care about anything but .500 and below lift numbers.

God damn, would any body like to kick on me for my mildly ported heads only flowing 257@.600? Car ran 11.3's at 3700 lbs on drag radials, Flow #'s aint everything. Does that mean my car wont be quicker with a better set of heads? no, just saying 278 cfm's can still make some good power and he said he got them at a good price. Makes since to me to buy inside his budget

.500 and below lift numbers? You just don't know anything.

Honestly know one can tell how that head is going to perform from flow @ .7 post up the rest of the flow #'s.

that does seem low, but why have them tested at a level you wont use? That doesnt make since to me. Also why have another shop redo a companies heads? To me it only makes since to let the whoevers heads they are redo them since they know how everything on that specific head is done. MTI heads let MTI redo them, AFR Heads let AFR redo them etc etc. JMO, have them reflowed and post the #s at resonable lift #s

We encourage anyone buying a set of heads used to send them in to us to be checked and also to be freshened up. We offer this service at a very low cost. As far as flow, it is difficult to control the flow of our heads once they leave our facility and have been worked on by another shop. This is not reffering to the quality of work performed by other shops, but we wouldn't take a new Z06 to Ford to be altered or worked on.
There are many things that can affect the flow of a head. Something as simple as the size of a backcut can change flow by as much as 15 points. The smallest movement of material in the runner can also make a huge difference.
For about the last year, we have included a flow sheet with our heads. These sheets are specific to that set of heads and we do stand behind these numbers.
If you would like, we will be more than happy to send a call tag to pick up these heads and look at them. We will flow them on our bench and see if the problem with the flow can be corrected at this point. This work will take 2-3 weeks and there will no charge to you for shipping or any work performed.
