I'm getting a 331 stroker built for my car and I'm going to use my Cobra intake, 65mm Throttle Body and get 24lb injectors. Right now I am going to use the Trick Flow Twisted Wedge 175cc heads that have a 61cc combustion chamber.
I just saw that TF came out with 190cc Twisted Wedge Fast as Cast heads with a 66cc combustion chamber, for a few hundred dollars more.
Will those heads work with the setup I have, or will I need a bigger intake, TB and injectors? I definitely don't want to buy a new intake, so I'm hoping I can use my existing setup.
Any help is appreciated.
Thanks.

the 175 will work on the 331

but i would upgrade to a min. 70mm TB

there is no real need to go bigger on the heads if you are going to keep the cobra manifold.....

Thanks Reggie,
I knew you would come through. I kinda figured that regarding the TB and the intake as well.
I'll keep you posted.

My opinion is the TFS heads are better than the AFR's. The valve placement and valve angle put over the AFR performance wise. This helps with unshroud the valves and gives a straighter shot into the cylinder.
