Good eye, yes it's plugged. Otherwise it would cause a massive vacuum leak, until I get a new angled end piece and line. There were acouple of "FORD" engine blues used over the years actually, some of the earlier ones where pretty light were as the later color got darker. The color I choose is more towards the lighter "ford" blue but, it's not a baby blue.
I might be able to do a couple powder coat parts, like I said I've got the old set of cam covers and an extra non-svt uim. If someones interested I could do them up for $85 in most any color you want. I'll probably do them up red and just put them up on Ebay.
