Big block duster pain in the A$$

my 383 with hipo exhaust manifolds in my 69 gt dart with ps pb air , it was a boxed/open end wrench shorty that got plugs in and out . from the bottom mostly . but the install of that combo went in whole from the top with the hood on , but in/out from the bottom works great . everything can be set up and places correct without the flowing f....in words .
