Questions about a 2006 5.7

Did not want to start another thread about this, but is there an aftermarket piston you can buy to reduce the compression enough to use the post 2009 heads? Maybe just buying 2010 heads and 2010 pistons? Edelbrocks are 1500 a piece so no thanks on that one.

We are dealing with an 07, one intake valve seat gone, shrapnel in 3 other cylinders.
