ok it seems the intake is better on the ls6 and exaust is better on the tea's... the ls6 cnc didnt start until .200... threw me when trying to compare them..
but neither is better than the other straight across the board... the tea's are still cheaper. The CNC ported ls6's will cost $2,257.20 delivered. The TEA 1.5 rev2's are $1660 .. big difference

Couldnt line up the numbers straight across so its a little tricky looking at them. The way thier listed with the lift being shown different. one shows the numbers starting at 200 lift and the other 100 as well as one having a rating at 450. I agree the ls6 cnc'ed shows better numbers down low but not on all the exaust. Why is that? Also they are more expensive . I'm not sure what your apples to apples commment is about, the numbers are right there to be seen as well as I looked up the cost of the ls6's to my door. With some hand finishing it might be the best head out there right now but its still 2257.20 as compared to $1660. Thats 597 more. IF they would deliver that thing for a reasonable price it would be in the range but still more money. 940x2=$1880 + 100 for shipping would be $1980. But they want $376.20 to ship

TEA's are flowed with a exhaust tube making them appear to flow better on the exhaust. However, that's an insane amount to have shipped to your door
I'd be pissed!! anyways, TEA's heads are a awesome set of heads, and you'll definately be happy with them. I say you're in a win win situation. Go with what you're comfortable with man

Choosing your heads has to be in conjunction with choosing your cam.
With a FM11, I would go GMPP, however with a reverse like TR230 or X1, I would prefer the TEA's.
But when we look at AFR's for $2180 shipped, then it is not hard to see that GMPP's start fading away fast.

so with all this said, how do my heads look flow wise? those TEA's are mine...im curious for your opinions...since most of you know heads, and flow #'s better then me...did my heads do pretty good for what they are?
