The pistons aren't the same, but they will fit. Also, the E pistons are actually better considering they're not dished and will give you a higher CR.
All the other differences won't matter for matching it up either as they are totally internal to the block.
The only potential problem is of course the accessories, but considering I think all the accessories are the same parts (could be wrong), you shouldn't have any problem attaching them to the E block, you'll just need different belts.
