You should keep the decking of the block to a minimum, because it is already pretty thin compared to other engines, and has a weak spot at the front left head bolt that usually is cracked. The head can be cut a good bit, but expect other issues to start compunding it you cut an excessive amount. In a race prepped engine, a half a point of compression can make a difference, in a stock street engine, the difference couldn't even be measured. Since your stuck with the dished pistons instead of being able to upgrade to flat tops, there really isn't much gain to be had at this point that will be of any benefit.
