valve springs differn't cam

I have a F cam right now and it was installed by a previous owner. Is there anyway of telling if the springs were ever changed. I think they are factory but I am not sure. I have a guy at crane cams telling me that the springs should have been changed when that cam was installed because the lift is 100 thousadths more than the factory. And that my ticking noise is coil bind. I dont know what all that means this is all new to me.

No you cant hear it at all at idle but as soon as you rev it up or drive it it sounds like a steam locomotive comeing down the road. You can hear it both inside the car and out. I had the covers off and on several of the springs when the valve is fully opened I cant get no more than a .015-.020 feeler guage in between the coils. I was told that you should have at least .060. I am no where even close to that on several of these. I have replaced lifters rockers and rods with no results and even stepped up to 4 qts of 20W50 and 1 QT of that thick lucas oil and its still just as loud. Which from looking at my springs now that makes perfect sence. I could put the thickest oil on the market in the crank case and its not going to quiet down springs that only have .015 clearance between the coils. And thats just turning the motor over by hand. Not putting it under any load like 3000 or 6000 RPM's.

I could be wrong but I was told by a crane cam tech and a comp tech that its between the coils.
