Default Block Distorton @ what HP level?

After a few failed searches I thought that I would post this here.. I'm in the beginning stages of forging and stroking my current LS6 block that is in my 02 Vette. Before #2 went I was at 657/562 with 8.5 psi. I have heard through others that there is a hp limit that you need to be cautious of before you start seeing problems with warping blocks, etc. Therefore they tend to use something like an C5R or an iron LQ9 block for the added strength.

Those of you with high hp builds and have used an LS1 / LS6 block, what do you feel is a safe HP level to where one might not have to worry about warping the block? With my combo (still in planning stages) we are estimating around 800+ RWHP.. Can the block handle this for thousands of miles and be somewhat worry free during that time?

I would appreciate it if those of you with similar setups tell me about your experiences and what to plan and build for so you would not encounter such issues with your block.

Thanks!
