Trick Flow small block heads

Okay. Finally got my Trick Flow head 394 Dakota to the track for some test runs. Damn Covid!!!
It went 6.64 at 101 mph in the 1/8 mile.
The Dakota race weight is 3710lbs with me in it. I'm 180lbs.
I'm happy. I think 6.64 calculate to 10.50's in the 1/4 mile.
Engine specs are:
394 CI
3.79 stroke Mopar forged crank. Eagle H beam rods.
4.070 bore Weisco flat top pistons
Trick Flow 190 CC heads
Lunati flat tappet solid lift cam .581 int .601 exh
M1 intake
Com Cam magnum 1.5 roller rockers
950 carb
No hood scope and thru exhaust.

What sort of duration is the flat tappet cam on the inlet / exhaust if you dont mind me asking?
