I know I want one of these heads, I've looked at others and nothing was appealing to me. I've got a 383 LS1 in my ext. cab silverado with: F13 cam, FAST 90/90, full bolt-ons, and patriot heads. I've just finished nursing school and it's time to upgrade! I know both are bad-*** heads, just don't know which one yet. I've got about a year to decide, just wanted ya'lls input.

-TEA stage 2 LS6 $1745 w/o core ; $1320 w/core
-TFS 220 as cast ~$1700
-TFS 215 CNC $2395

 

My bud has a 383ci with trick flow 215 heads. he makes just over 500hp and 466tq on a stang dyno. My 402ci does not out pull him by much in a race from a roll. His car is a m6,12 bolt w/4.11's. same as mine. You know where my vote is.

 

The as cast ones would be the best bang for the buck

 

go with the tfs 215, thats probably what i will be doing if i ever get new heads

 

also look at the PRC 225 if with in your budget.

 

Call TEA since they did the TFS ports they can give you the best advice...

 

What cams are ya'll running? Also, what heads do you have?

Thanks for the replies!

 

TEA LS6..

 

Contact Advanced Induction they have a program for 243 heads with a 226 intake runner that are out flowing trick-flows of the same set up. Contact Phil or Ron great guys excellent customer service bar none.

Same heads am running right now.

 

Tfs 220 as cast with clean up work from vengeance racing are a great buy. I would get the trick flows for the thicker deck and 13 degree valve angle.
