i agree..i was really impressed with the mid lift numbers of these heads and to think they cost about the same as the other heads i flowed

tried to compile the data for better comparo...the TEA heads are a used set that I recently purchased and supposedly were "hand worked"...the stock LS1 numbers I got from data files that have floatin around the 'net for a number of years

Kind of shows me you have to weigh out if it's worth it to you to pay for the LS6 heads when you can get 5.3's brand new for $1200. I've been eyeing the PRC's. They have great low/mid lift numbers, and have consistently layed down good numbers from what I've seen.

Patriot's ported LS6 heads are $1295....

oh i know you aren't trying to step on anyones toes..i actually like the fact that you made a graph. It really shows how the heads flow compared to each other

well i changed my combo up and ended up picking up some slightly used afr 205's and had them flowed..mind you they have a 205cc runner while all the other heads i flowed had runners close to 225cc's

afr 205's milled to 62cc's

.......intake....exhaust
.100 68 ....... 58
.200 140 ..... 119
.300 202 ..... 172
.400 245 ..... 203
.500 277 ..... 219
.600 297 ..... 227
.700 295 ..... 231

as you can see the numbers weren't quite as high as the ported ls6 heads on the intake side but the numbers on the exhaust side were better then any of the other heads plus the small runner should easily make up for the slightly lower flow numbers. Another thing that surprised me is that they actually held their flow up all the way to .700 inches of lift while the stock ported heads all fell off right after .600 inches of lift. Overall they flowed just as good as the ported stockers but they only have a 205cc runner so i should be happy once i put these on
