Cant remember how much it was shaved down unfortunatly unless i can get a thickness measurement from a stock head and compare it to mine but idk if castings are consistant to where i can get an accurate reading.
I got it from American Custom Cams, told them what was working with and recommended this cam but wondering if they accidentally gave me a different one. I remember calling them up a couple months ago to see what the specs were but they get rid of there records after a year and its already been 3 years since i got it.
