I did the clay trick about 10 tens and i am done doing it. whats the least amount of piston to valve clearance someone has ever ran? And please give me positive answers,lol! Im ready to get the beast in!! HELP!

What cam are you running. I run a .566/.566 lift cam with 218/224 duration @.050 and I have 2.02 1.60 valves with stock untouched pistons.

You should have ask this question before you started grinding.
