Is this a good idea for my Block prep?

Cool! Ill just stick with the splayed mains. I don't see my motor spending its life above 7,000 RPM. It will be a street car.

For a motor that won't see 7000+, splaying the mains IMO is an unnecessary expense. The stock 2-bolt mains can support BIG power - more than most people think. There's an argument out there that drilling and splaying the mains doesn't really strengthen the block much more than just the 2-bolts because of the placement of the splayed holes.
