Vehicle is an M6
Stock LS2 bottom end
HPE S cam
American Racing 1 7/8 Headers
American Racing Midpipes with High flow cats
Fast 90mm
Ported LS2 TB
160* Thermostat
We gained a solid 30 rwhp over the ETP 5.3 230cc heads. Props to Trick Flow for making some very nice heads!

Let me get the straight, you are talking about the GM 4.8/5.3 casting that ET Performance CNC machines correct?. Their signature ETP casting is not available in the 230cc intake runner. Why not compare to the ETP 215?.

Wow, that's impressive, especially considering that ET's 5.3L heads are as good as the other CNC'd 5.3L heads on the market. Guess the new stuff really is a cut above. Well done.

Thats the way I see it too. It makes me glad that I spent the extra money on my TEA Trick Flows.

How is it not a fair comparison , 2 LSx heads were tested and one kicked the other ones *** . Least thats how I see it .
Test TEA 5.3's and then test TEA Trickflows and Id bet it would be a similar outcome .

I highly doubt the guys at ETP have been laying alot of claim into updating stock castings since they came out with their 11* line.
