LS1 Head Comparison Website
LS1 Head Comparison Website http://aaronmurray.com/default.asp?p...dflow_view.asp
Well, I got tired of keeping track of head flow numbers in a spreadsheet, so I created a dynamic page that has the data. The cool part is that the data can be sorted and graphed dynamically so I don't have to horse around with it anymore.
I'd like to have some more data to put on the site...I only have about 10 heads up so far.
NOTE TO MFGs/PORTERS: Send me your flow data and I put it on the site or direct you to a link that will allow you to enter it yourself if you choose. Please include:
Base head (ls1, ls6, lm7, etc)
Intake Valve Size
Exhaust Valve Size
Flow Bore Diameter
Stage and name for the head (ex: Stg 1X)
Does the head have any welding?
Flow numbers for lifts:
.050
.100
.200
.300
.400
.500
.550
.600
.650
.700
Let me know what you guys think and what upgrades I could make. I already have planned:
calculate I/E ratio automatically
EDIT: You need to accept the chart download (1 MB) to see the 3D graphs

I agree with you Mikey...but I don't know of a better way (than taking adv #s). There are other things that this doesn't take into consideration like chamber volume or quality of parts used...what to do...
Let's just hope the adv #s are close...if the shop is known for posting bogus #s or making false claims, then I won't post the data.
BTW, do you have any flow #s? I'll post your data if you send it to me (soslols1 @ yahoo.com)

Here is OUR newest flow numbers we have been using lately on Bears car and the last blower project.
Ferrea 2.02's and 2.05's tested.
.100 71
.200 151
.300 216
.400 260
.450 278
.500 297
.550 312
.600 321 Bruzinsky 3.90 LS1 bore slider.
.100 74
.200 156
.300 218
.400 271
.450 288
.500 298
.550 318
.600 329 Bruzinski 4.125 slider same head different bore size.
.700 337
.750 341
These are regular LS1 856 car castings but I have a set of 5.3 heads flowing the same numbers 216-218 cc's of volume. Really for a fair comparo that would be cool is to document for the record is to have the major porters to meet at one neutral shop, (Thunder perhaps?) show up with one intake valve, everyone with a head of the same casting # with there seat pre-cut to the porters prefrence and let everyone port there own runner right there on the spot, then document them right there on the same bench same day. Who would be willing to sponsor this? where would this be held? Would any serious porters want to do this?

Thanks Brian,
Give a call to the shop and you can set something up with Joe D, those numbers ARE real + or - 1-2% on other benches. A CNC on that port is definatly in order. BTW were kicking major *** with the 4.6 2003 Cobra heads too.

Thanks, Aaron
Nice I noticed that the MTI LS1 2E heads and the PP LM7 stage 1 heads are almost identical. Way off subject but I think it is cool as hell that you built your own arcade machine. It says you had a PC in it. Could you play all of your old favorites in one machine? Also I assume the joystick and buttons worked like normal?
Nice numbers Joe! Holy crap I would take brian up on that offer in a heartbeat 
340cfm@.750 is just plain nut's..not to mention the mid lift's are awesome too!
