Blockguard isn't really necessary, plus I hear that have some cooling problems. Don't know for sure on that one.

1 PSI= 10 HP give or take 2 based on tuning and it usually is only correct on lightly boosted motors (ie: basically stock with an average size turbo)
Blockguards can be safe if installed properly, which, most people do not do. I can't see how it could cause a cooling problem compared to filling the block
