If the cam is a symmetrical (same lobes on both intake and exhaust) grind and installed straight up they should.
I have seen, I think,
dual pattern cams with more duration on the exhaust lobe have the same valve lift at TDC when installed straight up, no advance or retard on the LSA
I was taught by some old time cam grinders and racers that installing the intake lobe advanced would help the bottom end, retarding it would lose bottom end and gain upper RPM power. I have tried doing that on the local Studka engine dyno years ago on one of my bracket stroker motors with a solid roller camshaft with a Jesel belt drive, didn't really see a significant change going to 3 degrees LSA either way
