This is Comp cams CS-282s solid cam . Any thoughts about using this particular cam?

With flat top pistons and 882 heads, probably not. The CR will be too low.

I ran that cam for years in a 400 with -12cc pistons and 64cc heads; it ran good, but it was hard to get it to ping. 10.2:1 or whatever, was too low.

882 heads are terrible. You need to get rid of those before you worry about what cam to use.
