im buying a set of these off another member, and im kind of lost on how the #1 runner works and installs any help would be great.

 

nvm i think i figured it out. looks like they just slip fit. Everyone like these? i did a search but nothing quite what i was looking for.

 

Yep, I like mine. I ended up wrapping them with DEI header wrap after the last rebuild. Without the wrap, and no coating, my underhood temps were prettttty high.

And yes, that cyl 1 primary just slip fits into itself, that way you don't have issues with the steering column. Just put a ring of high temp rtv where the joint is, and you'll be set. Mine hasn't leaked, and it's been about 2 yrs I think.
