TFS 215 as cast
I was just on Trick Flows site and it shows their cnc'd heads are 215cc and there as
cast version is 220cc's. Doesn't make sense. I'm glad the assembled one's are only 215cc but just seems backwards.

IIRC the "AS CAST" always came in 220cc only. I had their flow #'s on my computer at one point and they were really close to the 215 CNC heads. I think at .600 it was 315 or 317cfm CNC and 305 as cast but it's been a while since I looked so IDK for sure. At the new pricing they are looking REALLY good though aftermarket rockers or not
"as cast" means that they designed the mold off of the cnc'd heads.
due to casting issues they end up specing out a bit higher in the runner size.
it DOESN'T mean they cast the heads....at 220cc...then cnc them...
hence the "backward" thing with cnc'd at 215 and "as cast" at 220
