Default 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.

TEA flows with a pipe.

I've flowed them and let me tell you there is no comparison between a 15 degree and 11 degree.

I flowed my TEA's. They flowed well, but nothing compared to what they had on there site. Plus TEA uses a pipe on the exaust. That will drastically increase the flow as compared to no pipe. It's not a bad thing, just 2 diffrent ways of doing it.

Exhaust flow isnt as important as exhaust velocity for making power.

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.

I agree. Even though my heads didn't put out the number that was on the sheet, I was more focused on the HP numbers they had made in the past. I never had a problem bolting them down nor did I even bother to call and talk to them about it. It simply wasn't a problem since so many cars with the same program had already laid down impressive numbers. If I were wanting to use a stock castin head, I'd still go with TEA. They had great customer service and stopped to answer my questions everytime.
