Is this LA360 XE268 cam kit deal good for my combo?

Can you guys explain to me what advancing my current cam does for me. I understand raising the static CR (amount?) but will it also make it feel like a larger cam (or smaller)? If so.....what kind of numbers are we talking about? I bought this engine as "rebuilt" but did tear it down to bare block and reassemble. At that time I degreed the cam and installed straight up but I do now have a 3 position timing chain to install. I am somewhat concerned with the RPM range being 1500-4500. Not that I race it but power topping out at 4500 seems pretty low. Was told this is more of an RV (torque) cam. Thanks.
Please define ".......degreed the cam and installed straight up........"
