hey guys i just put a cam and duel springs on my 98 camaro and noticed alot more valve train noise, mostly sounds like lifter noise. the cam has less than 600 lift and the car doesnt have any sound dampening on the fire wall so its easy for me to hear. is this normal?

Very normal. If it gets to you too much you could up the lenght of your pushrods .025 and it will quiet down a little. I'm sure your fine you will get use to it.

why do people insist on saying this stuff? this isn't a universal rule, and could lead somebody out of proper pre-load range.

ive noticed the noise is worse as the car gets hotter. im going to change oils and see if it changes any. it has 40 psi at idle so it cant be that.

My valvetrain quieted down after a couple thousand miles but really had me worried at first. The more agressive cam lobes snap open and close the valves faster and that accounts for some of the noise along with the stiffer springs. It's louder than stock but I have heard worse than mine.

its probably normal, mine has a lot of noise and it worries me, ive tore into my motor twice but all seems good. Just the nature of the beast.

i had some of the same issues and ended up trashing a good cam but it was due to a missing thrust bearing behind the cam gear. after swapping cams and lifters the noise wasnt there for about 100 miles but now its back. i think itl be ok now its no where near the way it sounded before.
