Ok, I won't touch the cam.
Now, in regards to my pistons, which are KB 11.0:1 hyperuetectics. The tops of them have a little bit of a dome to them. Can I take a piece of emery cloth and just lightly go over the "sharp" edges just to remove the potential stress risers; potential starting points for cracks? I know not to take to much off because I don't want to throw the balance off.
Also, anybody know of a place to get a decent set of full roller rockers for under $180 for a set of '74-'78 era 333882 heads?
