I was not there.The man that owns the heads told me this.
I will submit a head to any independent test.I want a magazine to do a head to head flow test shootout.I will call monday and talk about setting this up.

BTW our two heads were the most out of any LS1 head ever flowed there!! I'm sure both sets of heads will work great.

There are derivitives of this head, with a 2.08 LS1 stem valve the head flows 320 on intake once it is hand finished on a 4.00" bore, we shrunk the CNC program .030" to run a 2.05 valve and ran it through a few sets of 6.0L heads and these flowed 320-325 on a 4.00" bore fully hand finished, once again there are just a few sets of these, and one of them belongs to a Corvette buddy of mine here in BG. None of these heads flow well on a 3.90" bore because they were not designed to. It knocks about 15 cfm off of the port flow on a 3.90" bore, due to the air flowing out into the 4.00" size of the 6.0L chamber and then hitting the ledge of the 3.90" bore. So the only good way to use this smaller Judson port on a 3.90" bore is to use a LS6 head, due to its 3.90" chamber, these heads flowed around 320 cfm @ .600", there are 2 sets of these in existance, one is on my car and the other set was sold to GMMG and installed on a customers car that made 433 RWTQ and almost 450 RWHP. I will post the graph for your viewing pleasure.
I think I know of the heads that were flowed at High Flow, they were basically a Stg 2 intake with a N2O exhaust that we flowed on a 4.00" bore and I guess Mike flowed them on a 3.90" bore, and the report I got was they had the highest flowing exhaust port Mike has ever seen. BTW, these were NOT high dollar heads as the guy that owns them traded a set of 5.3 that he used for a while, had some problems with them (the only set ever!) not due to anything we did, and to help him out I gave these 6.0L heads to him for his used and torn up 5.3 heads, a gift to say the least, not a $$$ set of heads.
So please, before you start running off at the mouth about something that you don't have a clue about you may want to think twice, because this is slander, and slander is a chargable offense.
BTW, we flowed a set of Terry's Stg 2 LS6 STYLE heads and they flowed 185 @ .300" (15 down from our 5.3 Stg 1.5) and 299 @ .600", not too bad, but the port volume was 230cc+, so Terry you need to recheck your port volumes, but if it flowed those numbers at Mikes then congrats to Terry, too bad he can't repeat those on every set. I could write a book on how hard it is to get every port on every set to flow those kind of numbers, as I'm sure Terry could also. The only way anyone can be assured of consistent flow numbers is to buy a CNC ported head and then fully hand finish it (by a true expert). Otherwise we all have some better then others, just like our 5.3 heads many have flowed 300+ all over the country, but some have only gone 285. So then you have customers that make 440 RWHP and some that make 390 RWHP. So until the customer can afford to get the heads fully hand sanded by an expert, then it is a crap shoot as to what you are going to get. One thing that is not a crap shoot with our product, having a torn up engine due to valve breakage, spring breakage, or seats dropping, you truly get what you pay for!

I can reproduce this every time.After I hand blend the bowl area every set will be within a couple of cfm of each other.I will do this for the standard stage 2 price.I posted in an earlier post that the 2.055 valve will be an option for the stage 2 from now on.
I don't care what people have claimed the heads flow in the past.I now flow test every set before they ship.If they do not flow what I advertise they will not ship.

I will let you pick out the set.This way it will not be a ringer set.I am very confident in the heads I produce.In the past 2 weeks,I have done many flow test to make the heads as good as possible.

I have been checking them the last week and a half.If for some reason a customers head does not flow what I advertise,I can fix them with a small amount of work.

In the past I have not tested every set.I would test some periodicly.I have always hand blended the valve bowl area.

If PP made a quality product why in the last year...
bad valves
bad springs
retainer issue
oil consumption issue
seats that fall out of the heads
changing from teflon to stock or viton valve seals
just starting to finally machine the chambers on 5.7 heads
bowl clean up but not checking on the bench to see if the heads flow correctly until last week.
That stuff is obvious for the most part and should have checked from day one when PP opened the doors. They are still just learning to get around too doing it. That's a stout list of issues. It's good Terry is working to correct this stuff but seems like PP should have worked harder to correct issues before sending this stuff to customers.
When that sort of thing is taken care of I too think the negative stuff about PP will stop.
