You'll need to take the valvetrain measurements (lift and duration)in order tocompare them with the cam's manufacturer specs.
Or just take the cam over to a good machine shop and have them compare it to the original specs. This assumes you know 100% what cam you have.Sometimes youcan tell if the cam is worn by visually looking at it,(when it's out of the engine of course). Just look at the lobes and see if they're scored or burned on the sides of the lobes and shiny in the center.

IF the lifters were bad, rocker arms out of adjustment, the oil not changed regularly, and/or the motor consistantly over-revved, the cam could be worn also. As for a noise? It may be valvetrain noises (tapping) coming from the top of the engine.

You didn't give any details. Why do you think your cam is wiped out???

The engine would run like crap if one of the cam lobes was wiped out.

i dont think my cam is bad but
the cam thats in it looks like that i thought it looked odd but i was told by a couple of shops that it SHOULD be fine you think thats my prob?? i have an E-303 to replace it (stock cam is in right now) but if i put the E-303 in there im worried bout clearence issues my motor was 0 decked and the heads were shaved 0.020" would i have clearence probs?? what springs should i use??

as long as you are not running 1.7 roller rockers, the E cam will fit fine

Stock 87 - 93 5.0L engine with stock heads?
The "E" cam only has a 0.498" lift; you will be fine. Once cam lifts go above 0.512", you have to check valve-to-piston clearance and consider flycut pistons. You'll be fine with the "E" cam.

how do i know if i have 1.7 roller rockers cuz i do have aftermarket roller rockers but i dont know which ones they are they were on it when i got it

if your rockers are aftermarket, they will say if they are 1.6 on the top of the rocker heads. Change out the cam if you have one you will be fine that E cam is nothing big just make sure your valve are not over 194. put better springs on if you dont already have some, go just alittle higher with the spring max lift then what your cam is spect at just incase you have 1.6 rockers. 1.6 from 1.7 is not a large number when it comes to lift it just makes it easer foryour cam to push the valves down. Your problem might be your timing chain it will go bad long before your cam will unless someone didnt ajust your valve train correctly. good luck
