Power limits for LA small blocks?

I saw that this question has been asked before but I'm curious if anyone else has any recent builds or experience. I'm planning to build a small block stroker out of my 360. I'm going to use a forged kit with flat tops most likely and I would really like to put a procharger on it. I'm guessing the final number will be 600+ hp. Will a factory block handle that or will I have head gasket problems because of the stud lay out.
