I have an opportunity to buy a BBC from a friend of mine who owns his own shop (468ci). He told me he has numerous BBC heads and I can basically pick the ones I want. I was planning on getting the casting numbers of the heads so I can see exactly what I'm getting. Do any of you have a link to a site where I can enter the casting numbers and get the specs. on the head? Ideas?? Also, I would like to put a serpentine setup on this engine (it' would go in my '90 K5). I see these kits for SBC's but not for BBC's. I have all the accessories I just need the brackets. Should I just go to the dealership and buy the individual brackets for an early 90's 454?
