Did you consider going to their web sites and seeing for your self what they are designed for? Please read this you will be able to answer your own question. It's from their web sites.
525 CAMS - A real workhorse, designed to increase torque band width and increase fuel economy. Great bolt in camshaft upgrade for stock 88” & 96" engines also performs very well in 103" strokers. Produces strong low and mid range power with a linear horsepower and torque curve. Can be used with factory valve springs, pushrods and lifters. Increases throttle response and eases starting. Will also respond well to increased compression and cylinder head work. RPM 1,750 – 5,500
551: Designed for engines with 96 to 106 CID and 9:1 to 9:9 compression this is a bolt-in cam set designed for stock or mildly modified touring bikes. 551 cams are not recommended for compression ratios of 10:1 or greater. Greatly improves low-end and midrange torque, strongest from idle-4000rpm.*
If you need a boost, you have a 88.
