I have honestly not seen much of the Trick Flows. With everything I've seen of them today it looks like I cant go wrong. Even though they come cnc ported has anyone truly opened them up yet with bigger valves and some hand porting? Intrested to see how far they can go.
They flow as advertised up to .500 lift. After that they maxxed out around 280cfm. Advertized at 302cfm. With a 2.08 valve, removing .04 from common wall, raising the roof .150, and widending the comb chamber to 4.05 flow picked up 20/25 cfm through .500 lift, still maxxed out at 285cfm. Almost 225cfm at .300 lift. Exh picked up a couple % over advertized with no port work, just widening the chamber. Chamber is made to fit 318 bore at 3.95 as delivered. Valves I put in them are from trick flow for their ford head. Correct length but 5/16 stem, so guides had to be changed. 2.08 valve is 15 grams lighter than the 2.02 valves supplied in them. Hopefully have them on the engine and at the track in mid march
