Cam intake closing importance

Hello all.
Running 318,30 over, KB 167 0 deck, stock length rods, stock crank (3500 miles on short block). Edelbrock 60779 heads ( not ported). 1.6 rocker arms compression ratio at 9.8:1. I was running a Mopar p#p4120653 “528” solid flat tappet cam ( it was on the shelf).
Pumping hot averages 135 to 140 psi. Intake valve closes at 72 deg.
Engine has put the car at 13.0sec with 3.91,28” tire at 105mph. 60 ft average 1.88. Running a 3200 stall.
The dynamic compression works out to 6.41 ( 528 cam). I need to run engine to 7200 rpm shift points to get the job done in the 1/4 mile.
I’m going to use a hydraulic roller . The cam from Hughes is looking to close intake at 39 degrees. What effect does the early valve close have on cylinder filling vs the 72 degrees from the old “528” cam.
I want to select the best of my options. Most calculators online suggests 8.5 dynamic. Is this not going to limit max cylinder filling ( roller)? Last thing I need is to go backwards with a new cam selection.
Any help is very much appreciated.
Thanks,
John
