I'm hoping its 10-15. From everyone I've talked to, 10-15 seems to be the consensus.

You can expect 15chp from 1.6:1 RRs on intake & exhaust on a late L98 and from 1.6:1 RRs on intake with 1.5:1s on exhaust for an early L98.

12-15 CHP is realistic going from 1.5 to 1.6 RR. If the stock rockers were real bad, you might get a few more. It's a good change, easy, can't say inexpensive.
Buy good ones tho'. Look what happened to the Jegs car this past weekend with his RRs. Granted, most of us aren't running those lifts or spring pressures, BUT, ours run a lot longer and RPMs a lot more varied and wider range than his, and we subject them to a lot more heat variations. Don't think for a second that valve float won't tear up a rocker, pushrod or valve.

Not preaching, they are a good bang for the buck that can be used in more situations than a lot of other aftermarket parts.
