I was wondering if anybody had the tfs heads on a 2v and has had them ported and polished, what kind of power did you see as well?

why would you want to port them?

I would guess to get more HP and TQ.

youre aware that these heads will support 9000+ rpm out of the box...

I seen the new trick flow heads, they are 195 cc heads. Shouldnt need to port them for sure. But if he has the 185 cc heads , depending what he is shooting for hp wise i would port them , and a good port match.

i was told at the dyno they will support 7000 rpm and also i am looking into it to make more power, i have a 301 stroker kit, the heads, tfs track heat intake manifold tfs upper intake and a bunch of fuel system upgrages, also i have a blower that i have not yet gotten on the car

scott4.6

In your case i would port them .

I would do 4 valve swap

no, your bottom end will support 7000 rpm, theres NHRA ProStock guys running these heads out of the box to 9500+ rpm... trust me save your money and out it elsewhere

How much power are you looking to make? If you are looking to make 700-800 at the flywheel on a supercharged combination the 185cc heads will do that all day with out touching them. If you are looking to make more on your stroker combination go with the new 195cc R series head. With the 301 you have enough room to support the bigger 1.90" intake valve and it will make a ton of power. If you have any questions let me know.
