I was at the not so local salvage yard looking at a 79 mustang with an inline 6, I knew I needed the D7, or the E0 head, well on the physical intake part of the head it said D8BE but on the exhaust manifold it had the D7 number, is this a different head? The motor looked pretty nice like it had been through before it was salvaged. the 79s only came with 200s correct? thanks for the help, oh and one more thing that was the only small 6 in the entire yard, where as I know I saw at least 5 bigger 6s.... thanks again, Tommy
