which heads will giveme more power? Trickflow as cast 220 or total engine airflow stage 2 gm 6.0 truck heads? People are telling me tfs are the way to go, but tea have better flow numbers across the board. I have 215/230 630/693 117 cam

 

post up the specs on each head. ex CC, CFM,

 

I have seen nothing but killer numbers from TFS but you have to run aftermarket rockers I believe. So if you don't already have them those heads are a lot more expensive than the TEAs. If you aren't building and all out race truck just something fun and quick go TEA and spend the extra money on something else

 

Il post the exact flow numbers soon I am getting ready for worknow but www.trickflow.com look up cast 220, and the other is at www.totalengineairflow.com then under gm ls6 6.0 liter stage 2 thanks

 

Thanks the price difference between the two is only 315 more for the tfs and I was planning on doing yells terras on either head you think the tfs will put out more power even though the flow numbers are down, probinly because they are the as cast version vs cnc version? CNC version is 700 more than cast

 

flow numbers tfs inteke-exhaust/tea intake-exhaust
.1 67-47/ 67-54
.2 133-104/ 139-120
.3 211-167/ 219-179
.4 261-202/ 271-224
.5 292-222/ 308-248
.6 305-233/ 320-255

The tea are cnc ls6 heads they said. The truck heads would had slightly lower results the tfs are not cnc

 

I don't know if you have any heads yet but I have some Dart 225s that I have for sale. You could buy them from me and some YT rockers for less than the price of either of these. They have been completely rebuilt. The reason I want to get rid of them is I want to go more of a max effort build on my Camaro.

 

I suggest talking with Richard at WCCH. He will point you in the right direction.
