Decking 241 heads
I am trying to find out how much I would have to deck a set of 241 heads to get 10.5:1 on stock ls1 pistons. Also would I have to worry with valve clearance on a .580 lift cam?

Another option would be to run .040 thick gaskets (I believe stock is .053) for almost the same results without the machine shop labor. Of course that is assuming your deck surface is square and free from imperfections.
General rule of thumb is 1cc for every .006 removed on LS heads. Chamber size & shape will change that figure for different engines though.
