Hi - I have been a hot rodder for many years, strating out @ age 14 with a '55 Chevy Belair, later adding a BBC 427 coupled with a Muncie M22. After many years later, 1 wife and two kids, I have another '55. This time it's a 150 coupe. I'm currently gathering parts for a BBC I recently acquired.
My first question is on the casting numbers on the heads. It is 398781. The are open chamber& oval port. I can't seem to find any numbers even close. HELP!
Thanks
