All LA small blocks are wedges. So are the B and RB engines. The Hemi's are not. A 413 that is a Max Wedge has special heads, cam and high compression. If you don't know what you are looking at you had better get all the numbers you can off the block, heads, intake (if it has one) and all the rest. Otherwise you will be just taking the guy's word that it's a "wedge". Ya, they all are.
