Re: Vlll1TDJ
from what ive been told and have gathered over time from motorheads and old hot rodders...the X after casting number is for experimental heads...not necessarily one off heads...just a change they made during the run and remade it with the change.so then they had a way of identifying the head with change and one without during the run of the head.
