cam rpm range on stroker

Thanks guys so far it seems tough to get a cam recommendation from the email route filling out their somewhat detailed request form.I did get one from hughes
HUG STL6064AS-8

SB SLD FLAT TAPPET CAM 260/264 -108ÂșLSA

.410"/.414" LOBE LIFT
seems to be in the area thats being recommended here but then I see this comp cam that I was 1st looking at 20-633-5
260/266 @.050 but the lift is .558/.555 what kind of difference is that lift making,the heads will kinda peter out at around .550 lift does the "extra" lift still help?


Also, you need to see the advertised and @ .200 numbers to actually compare two lobes. And that's still not the full picture.
