Theres a thread that shows chamber size, valve size, and shows how to calculate to see how much to mill ur ls head. If someone can point me to the right direction that would be great thanks guys...

 

It takes somewhere in the neighborhood of .006 - .007 to remove 1cc from the combustion chamber. You normally want to stay under .040 to keep from having piston to valve clearance. You can go more, but will probably run into intake to head sealing issues. Hope this helps. If not just use the search button up top.

 

Thanks for the info bro. Ima do a 6.0 n im just wanna see which heads to with and how much to mill. That way I can order a cam n use an intake for the heads.... I already have a 08 intake with a 90mm tb cathedral, but wanna see if I should go with a l92 setup....
