A tidbit for interest.....
"The Iron's ports are all over the place as far as casting alignment and sizes go. Number's 7, and 8 measure right at 1.900" tall, where the rest average out from 1.950" to 2.010" tall. The picture shows the odd (1-3-5-7) side of the intake, and clearly shows that you'd have a pretty good vacuum leak at #7. Same goes for #8 on the other side."
