Trickflow as cast VS ported flow #s? Does anyone know what the trickflow as cast heads flow? I see they had a flow chart for the ported ones, but nothing for the as cast heads. I'm just wondering if they would even be worth buying since theyre $500 more. My tuner just recommends the as cast heads since he makes good power on those.
i dont know the flow numbers but Vengeance and Tick Performance both use the as cast heads in some of their h/c packages so they do make good power, but they usually fall short of the cnc 215's. The upside of the 220's can be ported in the future and they would probably work better than 215's especially on a stroker motor.

Well I'm going to a stroker whenever this motor dies. But I could pick up another set when that happens. He made 445whp through as cast heads with a 228/230 cam with a completly stock LS6 intake and stock TB.

I have the As cast with the upgraded springs and milled them to 60cc's , I got them from vengeance. The combustion chamber is cnc'd but the only thing that isn't are the runners and I see room to grow in if they get hogged out!
Gotta love those TF's

in the for sale section someone has some 220's that are ported but by hand, i guess that works ok but if the workmanship sucks, so do your heads for the rest of time you have them.
Since i dont know any genius porters in my area, and the only other person i really know of is Tony Mamo (I dont know if he would do TFS since he's AFR). I would rather stick with the R&D companies put into a good CNC program.
