I purchased 2 blocks and 2 sets of heads here are the codes on them. I am trying to figure them out. A 400 YD Block, 9799914, 0267397, 20X123644, K189. The 350 WV is supposed to be a 350 HO and here are it's codes 9790070, 039469, 29R162464, H188. the heads are: #16, K189 and the #46 B189 & B209. I am trying to figure out which engine head combo to go with and since crane cams doesn't exist anymore I don't know what cam to run it. Please help a novice figure this out???? Thanks
