Did a head swap for zamboxl yesterday at my house.
He used PP heads and I snapped some pictures for everyone to see. Heads looked okay to me, he did say he touched up a couple small parts himself.

Not trying to be negative,but that is some ugly cnc work.That is the worst I have ever laid eyes on.

 

You can be as negative as you want.
These aren't my heads, so your not gonna offend me.
I just posted these so everyone can see.

 

That is standard on patriot heads

I assume once hand finished they will be good right.

 

hey they might not be pretty but they got the job done. The car aint tune yet and it iddles like *** but i could feel a difference already, for sure. before the car felt heavy, now it feels like it just wants to go, i havent reved it up yet, taking it easy for now, but damn the rpm's climb pretty fast, and she pulls like crasy even from down low.
hey jeremy what's that site again where you posted the last pics.

 

I don't know, when I got my Patriot heads they looked nice and smooth to me.

 

In their defense....... Bang for the buck is the whole concept here. The CNC "steps" are rather large. Probably around .050" and looks like it (the CNC) takes the material all out in one pass that causes chattering of the tool. Have you seen the GM CNC heads? They look similar. Really fine steps (.005") and roughing with multi finishing steps would produce very smooth cuts, but would add many, many more hours per head to do. Price sky rockets. I have seen the other ads that want thousand dollar core charges, but Patriot provides brand new one's. They should be hand finished as I am doing for Max effort but out of the box they are way better than whatever you had on there. They are best classified as production porting verses custom porting. Bang for the buck. How much did you pay for your "pretty" heads?

 

I am by no means a CNC expert but my Patriot heads looked alot better than that when I got them. Mine were hand finished though, dont know if that makes a difference.

 

Does a pretty finish on your heads make power? I dunno, maybe a little. But it couldn't hurt. And a prettier finish would tend to show a more "quality" cnc job.

 

Two of our local car club guys sent their PP heads back after seeing the shoddy ports on the heads they ordered.

You get what you pay for, period.

 

I think once you get them hand finished they flow very well. Looks has nothing to do w/ performance. Im mainly getting mine hand finished to reduce carbon ect.

 

if thats the case... than you havent laid your eyes on enough heads.....

ive seen MUCH worse than that... and for being PP heads (economy) i think they look nice! if you really want a glass finish just touch them up yourself...
but i think there fine, have fun with them!

 

One more thing.......... I own a CNC but I saved money buying my Patriot LQ9's.

 

Not only did you save money, you saved power too!

thanks man i will

 

I think we all know these aren't the best heads ever made but he did make nearly 400 last night and 390 TQ.
That is with mac mid length's, stock NON PORTED TB, LS6 intake, COMPLETLY STOCK EXHAUST (minus the cats) from the Y pipe back, 6 speed, pulley, TR224 cam, and full tune.
Not to bad for having stock exhaust, midlength's, and stock TB.
Car pulls nicely. I would have liked to see the HP numbers continue to go up a little above 5800 RPM's, but what was neat was he made over 390 from 5600-6500 RPM's but never hit the 400 horse mark.
For a set of cheep heads, you really cant complain.

 

yep cant complain at all
