Comp High Tech SS 1.7's FTW!
Yes but doesn't mean the same preload were actually put on both times. Long ago I had my cc503 installed by a shop who adjusted my rockers to 1/2" turn with my stock lifters. When I changed my setup a year later I did the work myself and used an 1/8" turn or so (recommend by Lloyd) again with the same stock lifters. I've seen people run between 1/16" turn to beyond a 1/2" turn with the stock lifters. You just never know considering it could have been doen by someone else before that has different opinions on preload and whatnot.
Dammit this had to come up the day I'm ordering rockers. Think I'll stick w the ultras unless someone can prove the SS are that much better.
The ultras are designed to be super light over the nose and very ridgid.

yea were tryin to find a good tuner around here to do a full tune. Not sure about LPE anymore since they sold. I think speed inc. is going to be our best bet, but it's almost 4hrs away!

There is nothing wrong with the ultra promags From what I've seen! The regular promags are the ones that seem to have issues.

does the rocker have more of an effect on valve speed than the cam? I always wonder why people step up the rocker ratio increasing valve train pressures and stress instead of going with higher lift on the cam.
I would prefer to get extra lift with the rocker as opposed to a bigger cam lobe. The taller lobe MIGHT be much "faster" that COULD result in a loss of valve control.

Rockers multiply every aspect of the cams profile, and also the springs rate in both directions.
