I have a perfect GM Gen IV bowtie block currently at 4.250 will easily go to 4.600 No trauma or damage... Still together as a nice 496...
We had it in a low hour 496 stroker and took it in on trade for building a pair of 572s with Dart blocks. I also have several Gen VI blocks at 4.500 or 4.530 If interested in the bowtie block send me a PM and I'll strip it to use the internals in a freshened 454 block/496.
