Has anyone installed the SLP 1.85:1 rocker arms. They boast "up to" 18HP increase. It seams like an easy bolt-on for those of us who don't want to change the cam. It may be a little pricey but I would appreciate your thoughts on this anyway.

That "up to" is nearly impossible[if not totaly] to reach.
The 1.6 rockers for the LT1 were supposed to be magic also,but once tested gave 10hp at stratospheric RPMs at a cost of $600.00 CDN plus instalation of a few $100.00 more.
Very ineffective as an upgrade !!!!!!

GM High Tech did the SLP Rocker Arms on an LS1 and I think it was a 22 HP increase..
I think its worth it, if you are not doing a cam.

SLP would never exagerate gains. Which "application" got the 40+hp and 60+TQ from LT headers that they advertise?
I think 10-12 is common and that's across the RPM range so its a decent mod if you have the time and the spare cash
