Break in has me a bit concerned. Comp cams says leave out the inner springs and use their break in lube. After installing a few of the springs I figger'd out these things are STRONG. (bent my valve spring clamp, had to install gussets on it)
I do have a set of springs that are a little looser, and a set of stockers. Would one of these latter sets be good for the break in? Or would it be just a wasted effort. As it is i have to pop all the springs off once anyway . also, should i throw in a set of 1.5: rockers for cam break in?
Any input appreciated,
TIA

run 1.5 rockers, and if your springs with a little less pressure can take the lift of the cam then I would run those. I always say a good long prayer before starting up a new engine and have yet to have a cam failure. I also stay away from overly agressive cams...

And they should know, right?

Yes- the cam specs and break-in recommendations are all based on 1.5:1 rocker ratio, unless otherwise indicated.
