I found it impossible to find ANY info about the new street/strip heads from Trick Flow,......so here's some info for you guys if you're looking. These are the ones in the New Products section of the new summit catalog that someone mentioned in here. I got mine ordered, but..... if you order them, they won't ship until the end of February, because they haven't even made them yet.

And this is directly from an email response from thier Tech department....

The components you have will be able to transplanted to our heads, So long
as your heads have a 2.20" intake valve. The exhaust port floor has been
filled in & the roof has been raised slightly.
You will need to use a SCJ exhaust gasket...
These flow enough air (334 cfm's @ .600" lift on intake, 223 cfm's @ .600"
lift on exhaust...) right out of the box that you can make 650hp with no
porting....



WOOOOHOOOO, looks good, can't wait.

 

If you want any inside info on the heads, call trick flow and ask for Artie. He is in the r+d dept for the bbf parts.
