Patriot Predator Flow Numbers!
Guys, these heads are a 200cc CNC ported runner. Not quite sure what heads you are comparing these to, but our heads flow right with other competitors heads while being 5-10 cc's smaller. Please let us know if you have any questions.

Hmmm, just looking at numbers alone, doesn't look like these pair up to an AFR 205 set as I was thinking, or others on here above. Is everyone contemplating these heads will be hand ported to push out some nice numbers?? This is what I'm thinking, but could be completely wrong...

Not sure where you are getting your info from but check the flow #'s Gunnar posted to these found at Speed Inc's site for CNC'd AFR 205's with 66cc chambers. http://www.ls1speed.com/artwork/flow/afr1510.jpg According to my research they match up very well espec considering the $500 price difference
"h"....142...202...260....303....316....323... ..24 9 cc's....Hand ported 205 casting
AirFlow Research #’s
205….145….210….257….290….301….308………205 cc’s...(205 w/ 4.125 #’s)
So I wonder if there is any room for a bit more porting for some higher flows for the guys who want good balance of power and power under the curve???
The Predators should represent a super value no matter which intake runner/combustion chamber/springs/etc. you choose. For street use, the 200 cc with the kind of high velocity energy that they'll produce should work great for most of us. I'm going to use them on my 408 with a 70 to 72 cc combustion chamber. For a more single-purpose, strip engine, you can go with the 220 or 245 and the price is still the same. I'm sure that the high-lift flows on those heads will be way up there but the low to mid lift numbers won't be as good for a daily driver.
I can't wait!

That makes 2 of us. 64cc chamber 200cc Predators should go nice with the new Street Warrior manifold coming out. I know what my next round of mods are!

PLEASE READ THIS POST IF YOU GUYS HAVE POSTED OR BEFORE SOMEONE POSTS AGAIN.
It seems many of you could use some help with the design/flow of these heads.
There is NO reason to port this head any further.
The point to this head is a great flowing head using a small runner. This has proven to be a successful combo with AFR/ETP/TFS/Dart etc. This head should make killer power, while having a awesome torque curve and great Throttle response.
This head is tailored to a specific crowd, and that is the reason they also have a 220cc and 240cc head coming out. Big Red has the right idea. Combined with the right set of mod's your could have a killed package with a head that is 600 dollars cheeper then the comp. Also on the #'s posted above the AFR 205's are on a 4.125 bore. That makes the flow number a bit better then if they were flowed on a 3.900 bore or 4" bore.
Speaking of which Gunner what bore fixture did you use?
Basically this head has the potential to compete with some of the other top quality heads but for a lot less money. Porting further would defeat the purpose. Now you are buying a head based on price, but by the time you take the head apart, have them ported, cleaned, reassembled, and re flowed you could have just purchased a ETP or TFS head. If your looking for a better top end flowing head I am sure the 220cc head will be better suited for you.
Hope this help's some of you understand this product. Only time will tell how good they are compared to the other big togs, and at this price I am sure we should have some people providing number's for us shortly.
Thanks Patriot for bringing another quality head to the market and good luck.

Anyone who wants to continue porting this head after purchase and match it with your 230+ cam, go right ahead. Don't be surprised though when another guy with an untouched predator head and a 220-224 cam eat's your lunch up to 5000 rpm.
I'm wondering how this head would do with a f13 cam (230"/232" .595"/.585" 112LSA). I was looking very hard into purchasing the AFR 205's at the beginning of next year and would be very interested in these heads if i am able to get good results with them. The f13 and afr 205's are a proven combo but If these Predator heads are made to be matched with cams below the 228 range, i'll stick with the AFR's. Guess i'll just sit back and see how these Predator heads do until i'm ready to purchase my heads in January.

Gunnar made a seperate post regarding this head, on a seperate thread and was completed on a 3.900" bore.
So now given this new introduction, you guys are screwing with my head in what to get now for Tqr II cam!!!!
Predator, TFS as-cast or AFR, ugh... how long do I have to wait now?
Those exhaust numbers are pretty high on the higher lift end.
Are they available unmilled in those sizes or are they general sizes and then milled down to the desired size?
It's just you.
+1 Predators + Weiand intake will be more than likely going on my backup forged 347.

A couple quick questions:
What would the cost be minus springs and retainers? I run a TR224 cam and don't want or need the added weight of a dual spring. I prefer to stay with the 918's as I have had good success with them and already have the titanium retainers.
Also, with the 59cc chamber, I know you replied that it's a combination of chamber designs and milling, but would I be risking piston to valve clearance issues with a 0.040 gasket and a TR224 cam?
Thanks.

The flow numbers look really good on these heads. And im thinking the 220 runner heads will go really well with my E85 383 Engine build that will be running a turbo at around 15-18 PSI.
These may end being the next best thing to running L92 heads especially for the guys running less that a 4" bore.
