Dyno Numbers, new problem.

IMHO stock rockers are perfectly fine. Even Harland rebuilt stockers are better and still fine for high power apps. Swapping rockers usually only creates problems. Which I regret to admit I have seen my friend endure with the Jesels after many many pushrod length checks and numerous retorques, and a few guys on here have encoutnered problems too. Stay stock on rockers.

i have been running the 1.8's for about a month now. don't know if i have truely gained any power. the sotp butt-dyno says i haven't lost anything. the rockers gave it a more aggressive tone once it comes on the cam. 3500 and up the hooker is screamin.
yeah it has a bit more top end noise, don't really know if its the rockers or the 918's, but i had some with the stock rockers/pushrods and .050" longer pushrods. i do get a little ticking now and then. its not a knocking noise, more like a header tick, or it could be the idler pulley.
all in all i feel that the 1.8s complemented my setup.

I think that with your cam those rockers will work. That cam is made for use with those rockers. Those are supposed to be quiet to keep from setting off the knock sensors. You have the whole package. Mine have been noisey from day one.
I think the 918s make noise too, I had them and went with Patriot Gold and it got quieter.

Do the harlan's use studs or the stock bolts?
(btw I have no idea if my rockers are the cause of my problem, but I cant think of what else it could really be)
