that cam is actually fairly typical for a std port window 440-ish sized motor in a lite bracket car.
although, its not what i would have recommended for the elevation you race at.
a little less duration, and a little wider lsa to help try and keep some of that precious air in the motor so you can get some work out of it.

those lobes will want a fair amount of spring pressure to maintain full control of the valvetrain with 1.6 rockers and 7200+ type of rpms.
i'd say at least 250 seat/650 open as a minimum.

all that being said, i dont think theres going to be any cam thats going to end up being some "silver bullet" type of cure.

if they are the newer version heads, i thought i saw where Brain said the low lift numbers were a bit soft OOTB.

i would see if you could borrow a dominator from a friend and see what that does.
