Flow Numbers, Int vs Ex, ET vs TEA This uses the flow numbers on the vendors web sites.
The ET 240 and TEA LS6 Stage 6 have comparable intake flows (within 1-2% at each lift). However, the TEA head has 10-15% more exhaust flow.
Is the difference due to testing differences or does the TEA flow more in the exhaust. And if the TEA flow more, does it flow too much or does the ET flow too little?
Presumably, if the ET flowed too little it would require a bigger exhaust lobe.

Not to mention, The guy I talked to from TEA (name withheld) talked trash about some other companies cylinder heads on the market. Like theirs was GOLD and the others belonged in the recycle bin.
"We know something about porting LS1 heads that no one else knows yet
, and our prices (which are crazy) are still lower than they need to be".

TEA makes a DAMN IMPRESSIVE stock casting clyinder head.
I had a stage 3 LQ9 head flowed locally and at the time it was the highest flowing head I had seen on my local bench.
Then I introduced the bench to the ETP 225's. Now the TEA head is #2. Still a bad *** head but those new castings from ET are damn nice.
I would say if your in the 1500-1800 dollar market TEA can make something real nice for you, but if you can spend 2200-2500 there is no comparision to the ETP's.
