Default Newbie question?

I did a search and couldont find anything. What is flycut? i am installing a cam, and keep seeing people say you will need to fly cut the pistons. Will i have to flycut my pistons with this cam 234/242 .600/.610 LSA 110+2. This is going with 243 castings with PRC gold dual valve springs, and stock valves that came with LS6 head. I had no clue going into this. Right now i got the heads off, and waitng to get the crank pulley off, but my air compressor is too small.

Flycutting is when you cut into the tops of the pistons in order make more room for your valves.

degree the cam, then check ptv. i would check, it should clear, but i would measure on how much it clears by. min of .070int./.090exh.
