I'm using the Speed Master 3V heads and intake combo. Performance is good but the overall height is taller vs the stock setup. So, if you are wanting to use the engine cover you may have to modify the screen depending on carb/air filter height.
I'm going back with the Sniper 2 EFI so I might get lucky, and it all fit under the engine cover. Will know the answer in a couple of months.
Another issue is this setups intake manifold hangs out further at the rear of the engine so the factory oil sending unit interferes with the intake. Have to use NPT extension to fit the sending unit or remove material from the intake. If you go with a small external oil pressure gauge in that location it may fit without an extension.
