Cam question???

[Al S]

I will post pic tomorrow on photobucket.

I have heard that cam and followers must be changed together. NO new cam with old followers or visa versa. Is this true?
Scorch marks – To me, that means the metal has been heated by a high temperature. Like an exhaust header pipe when the mixture is too lean and upon cool down that area appears blue/purple.  
I know, take a picture.

What do you mean by "scorch marks?"

Where are they?

Take a pic so others can opine....

I seriously doubt there's anything amiss. Cams are surface hardened and I think the followers are softer metal so if any abrasion took place it would be on the followers.

  I have almost 225K on my ‘90 80. Fairly good maintenance. The last time I replace a leaking cover gasket, I noticed that there was scorch marks on some of the cam lobes. Does anyone have the specs for the 2.0l 3A engines cam? I am replacing the cam followers and I wonder if I need to replace the cam or should I touch up the lobes with a little crocus cloth? Are new cams available? Any aftermarket cams?

  I think the cam is ok, good smooth idle, good running up to 5000 rpm. But what do I know.
