Nice looking installation!! love

I've been looking at a few Ford based forums and have been given a few ideas to check out.
Took her out for a blast at the weekend, once warmed up started missing, backfiring, with no power. Only change I made was a new set of plugs...could one of these fail when hot.

I've also decided she's running too lean, so I need to richen things up. To start with I'll close up the vacuum pipes coming from the inlet manifold..see how that works.
