Default Updated Cylinder head flow numbers spreadsheet
I have updated my cylinder head flow spreadsheet with some new information. I have broken it down by LS1, LS6, 5.3, and 6.0L

If you have flow information for a set of cylinder heads that you'd like to see added, please forward it on. The more information on the heads, flowbench, etc... The better. If there are any features you'd like to see added, please chime in.

EDIT: My webspace went away years ago, so I've removed the link and posted the spreadsheet here directly. Its a very old spreadsheet. But, it should give you some basic info...

I have it saved on my computer at work and I'll be glad to post it up tomorrow. I don't know why it's not in my imageshack anymore.

If only flow numbers meant anything...... Choosing heads based on flow numbers is like trying to determine which car is faster by looking at EPA mileage ratings.

Which makes perfect sence. Lower fuel milage=more fuel being used, more fuel being used=more power, more power=faster.

Right!..... so the '09 6.2L 4wd Tahoe (EPA est. 11/14 MPG) must be faster than the LS3 6 spd 'Vette (EPA est. 16/26 MPG).
