Awesome guys, this is really great! It's totally starting to make sense. Everything I've been reading about boring, honing and decking tries to explain so much at once it gets overwhelming. I know my block is a 2 bolt main, and finding 4 bolts is almost impossible to find. I found main caps for 70 bucks on summit to convert my 2 bolt to a 4 bolt. Shouldn't be too bad to have done then!
