New Sponsor! Trick Flow
#21
The flow numbers he posted were from the 215cc "As-Cast", meaning that they're not CNC ported. They have the same program ran through the casting process that the CNC 215 version has. They have a "cast" intake and exhaust runner and a CNC ported chamber.

ss1 that is correct, however that's how they are advertised so that's how I believe is best to inform everyone. AFR 225's actually have 229cc intake runners. It's just posting exactly what the manufacturer advertises.

Brian, I believe the confusion may be from Vengeance advertising them as 215cc before anybody else was really selling them. Trickflow and others are all listing them as 220cc now.

Welcome to LS1Tech.
I have their TEA cnc'ed 64cc TFS215's and flow number are higher than posted, 319.5/262.7 @0.600" lift.
ss1, you are refering to different heads. Here's the link for TFS215:

Question for Trick Flow team, what's the max bore, ci that TFS 215 should be run as is w/64cc?

I will check the cc of the runners on the cast heads and post pics when I get them next week. I ordered them thinking they were 215, but doubt the 5cc difference will affect much, hope not anyway. Coming from 230 runner truck heads I doubt I'll be disappointed

I have a pushrod question for TFS.
I believe the TFS heads use a little bit longer pushrod. I have also read that Spintron testing has been showing the 5/16" pushrods (any head) have quite a bit of flex (several test sites have reported this). Has TFS ever considered fabricating an LSx specific tapered pushrod in lengths say from 7.300" to 7.500" (0.025 increments) that would help minimize the pushrod deflection yet still fit within the stock head without machining?
PS: Welcome as a sponsor.

Thanks for the welcome.
At this point we have not done any testing on this.

As of right now I do not see a pedastal head coming out in any near future.

Just like anything else in building a motor, you need to check your clearances. In some cases they may clear no problem, in others you may get a way with clearancing the valve cover or running the spacer. We like to see .080" - .100" clearance between the rocker and the valve cover just to be safe.
