I have two old SS Street Hemi blocks that have been decked around .100"-.120". I wouldn't recommend doing that. On a stock block and heads, I've heard .060" is around the maximum recommended. I prefer to take as little off as necessary. It sounds like you need different pistons to me.

How much can a stock block be decked? How about 452 cast iron heads?
If either of these are cut, how much does the intake side of the head need to be cut? Anything else need to be machined?
Thanks, Brian
For every .010 off the deck surface the intake side needs to be milled .0123 , whether it comes off the head or the block the heads intake surface needs to be cut ... also note for every .010 off the block deck the valley end rails should be cut , .0123 off the end rails , just like the heads .
I have a 383 that's been decked .018 and a set of heads I was going to use were cut about .040 , with the intake surface cut the required amount , I ended up having to cut .075 off the valley end rails to get the intake tub gasket to fit right .
