So it looks like OOTB the TF small block head flows very similar numbers to what a BIG BLOCK Edelbrock or even a mildly cleaned-up W2 flowed when they were first introduced. Pretty impressive IMO for a true bolt-on head even if it takes a little bit of clean-up and an inexpensive 2.055" valve ( I presume they are 11/32 stem +~.100 SBC valves) to get a true 300CFM.

If your .400 lift numbers are anything close to 260-265 on a wedge motor it's going to be a really good broad torque street head, the valve stays open at .400 or above for a lot more useable duration than it does at .500 or .550.

Sometimes I think it would be good if Mopar guys would be thankful and realize just how far the aftermarket has come for a market that is probably 1/5th the size of the total SBC/BBC market.

Look like just the right size for any 390+cube Small block, probably a better overall value than a Victor in that to really wring all the power out of that head you're typically going to overstress a stock 59 degree block, not to mention all of the piston/valvetrain/header flange mods and expenses required to get there.
