<VV> To Ping or Not to Ping

As Bill mentioned, if you're having high Cyl head temps, you may have not deflashed your heads.   

Fathers of childhood friends of mine who worked at Chevy Tonawanda admitted that they didn't do much deflashing on the heads when they arrived at the plant. 

I've torn apart a bunch of engines as most all of us had, and some of them don't appear to have been deflashed much at all. 

If you're detonating, it's worth the work to deflash those heads.  Engine Rebuilds are expensive enough.
