Heres a couple of shots of my block. Is it me or does the bottom of the block look milled? Everyone I've seen has a little ridge along the sides of the mains? Would you 4 bolt main this block? I've heard some say yes and some say no. I got an all forged assembly going in and the YS to blow on it so I need to know if it's worth the effort to install 4 bolt main caps. Thanks for looking .
