Yes I know not to over cam the motor either.

I would be nice to find someone with the LPE cams and see what they think.

If I use 1.65 or 1.7 Rocker arms on the cam I have now will I hear it in the Exhaust tone as beening more of Nasty sounding Cam.

After doing more digging the Performance end of it I will not be picking anymore H/P from doing a cam swap $350.00 for the Cam anouther $300.00 for the liffters $40.00 for push rods ect.

So to get rid of the stock sounding cam Will high lift help out.

Increasing the rocker arm ratio will do little if anything towards the cam's sound/lope.

Not to nitpick Gregg, but reversion is the backing up of the intake air/fuel charge up the port and runners commonly associated with a long intake duration cam. The overlap of the exhaust and intake cycles pushes the gasses backwards through the intake port.

True. I should have said reversion harmonic pulse or something similar, but it is a cylinder charging effect caused by reversion. I hope people who might agree, disagree, or debate with the point I made would know what I meant.
