Re: Valve Spacing on Big Valve FE Heads
Thanks for the reply. I checked again as you suggested. The valve spacing is definitely 2.1". I also rechecked the casting number. It's possible the 6 is a 5, but the bottom of the number seems to be clearly a full circle. The F is clearly an F, not an R. The casting code runs vertically, bottom to top, to the left of the center head bolt. There are clearly five characters plus the dash: C(5 or 6)AE-F. On the right side of the head bolt is what appears to be a date code. The first character is blurred (could be 11 of H), followed by 23 (very legible) and then what appears to be a dash. It is oriented the same as the other code and also reads bottom to top. Is any of that of help?
