Got the bottom end of the 400 pretty much finished. Cleaned up the heads and before I even had a chance to magnaflux saw they both were cracked...one small crack at the steam hole, the other a huge crack from water jacket out. I found a set of heads I can get for a song, but I can find any info on the casting number. The number is 14101083. The only place I know to check #'s is ChevyMania.com, and there not listed there. Mainly just need to know valve sizes and CC size. Also, any major difference between heads manufactured for EFI and those made for carbed motors?

Thanks
