Question?
I have three sets of 427 MR heads just found out they might be the hard to find "Big F" heads. How do you tell this? the casting number on the C5AE-F is straight up and down with date code on the other side of the head bolt hole. I was just about to sell two sets and got to thinking on this of what I have here. Thanks for any input
