The 360 build that has more turns than Willow Springs

I have some fel pro SB marine head gaskets I was thinking about using in my build. I got them off of eBay for what I thought was a decent price. As it turns out I punched the number on rock Auto and if it weren't for their shipping I'd have been cheaper to get them there, but they didn't come up by year make model lookup.
Damn another AD just completely blocked this window twice while I was creating it.
