Question Is a closed deck necessary

Ok now we know the difference between the two, but is this really necessary if you're going for only about 300-325HP. If so what would the benefit be? I think this was stated above, but I would like some more confirmation on this, because I seriously considering doing it.

Most people will probably say no, IF you stay at that power level.
If your going Hi power like a couple of members are (over 400 or 450), then they recommend getting a closed deck block.

Nope.

I'm considering semi-closing my deck as soon as I got for the 400hp level, other then that, I'm not about to worry about it.

I think our head bolts will start to stretch before a cylinder wall breaks. For the most part the block is pretty stout. The stock pistons are the weak link. I'd bet with proper tuning a stock block would be able to handle up to if not more than 20 lbs. The only other weak link would be the stock valve train. The stock springs would have problems holding back the positive manifold pressure.
