New Stg 3 LS6/6.0L first shot off CNC Well, just finished the new program last night, ran some LS6 castings today, valve jobed a set, did a quickie hand sand, on a 4.125 bore the flow numbers are as follows:
.100 75
.200 152
.300 220
.400 276
.500 318
.550 334
.600 340
This is with a 2.10 LS1 stem valve, this port will probably take the place of our current Judson Massingill port, but is still available if someone would like. We believe this is the best overall port available for a street driven 4.125 bore engine. There are 2 different exhaust ports available, but the bigger that flows 280 @ .600 with a pipe would probably be the port of choice.
This port was developed in house by our new employee Michael Paris Puglease, ex SAM employee, who did the existing Judson port while employeed at SAM. Flow numbers on a 6.0L head should be comparable. This port will also available on a 4.00" bore LS6/6.0L, but we have no flow numbers at this point. I would anticipate lower midlift numbers, but still generate 335+ @ .600". Thank you, Brian Tooley

All of this was done with a CNC, if so that is freaking incredible. Was the hand sanding done to blend any rough edges or was it something that is important for this specific port job to obtain those high numbers? I hope the guy from AFR reads this and realizes that LS#'s based heads can flow given the right port job.

I think AFR now realizes how difficult it is going to be to outpower someone that has years of experience making LS1/LS6 heads flow and make power, when they have been trying the same for just a few months. Just like most of the stuff we CNC port and hand finish, it has always outpowered a simple CNC ported and not hand sanded head, its just common sense.

Brian,
I'm thinking of sending my 6.0l heads up there and was wanting a ballpark price for the following. The CNC porting, installing bronze guides, 5/16" stems, seats for a 205 valve and installing dual 1.550 springs. I have all the parts, so it would be just labor.
thanks

On a serious note that's amazing flow! Makes me wish I had a 6.0 w/4.0 inch bore or 4.060 instead of a 5.7 going into the 91 RS.
Great numbers!

I wish AFR would try to get there heads out regardless of the flow numbers, barring any physical problems which I'm not saying there are, so aftermarket porters can start working there magic voodoo on them.
Brian if you get the chance can you flow these on a 4.03" or so size bore?

I agree with the AFR statement, I have a customer that is trying to make around 1200-1300 HP and needs this port we have run through a set of those heads!!
UPDATE TO THESE NUMBERS, We flowed the second set of customers heads today, same LS6, 4.125 bore, blended a little different, mid lift numbers were down a few, but they flowed 343 @ .60" and 350 @ .65"
Still with the 2.10 stainless standard valve. I can't wait to see whats next!!!! 
Do you have to move the guides to fit a 2.08 or 2.10 valve? Nice work BTW
