Good luck with the plenum hope it all goes smooth and start soaking the 4 corner intake bolts in PB blaster or something days in advance and that no guarantee they wont brake.
its the worst part of the job if you get them with no breakage its about a 2 hour job least thats about what it took me and i broke 1 bolt. the plenum post here is great to read a few time.

 

Thanks. Read the plenum post. Should come in pretty handy.
