Lesser of two evils - screamers

Alright gents,

I'm broke and only have two manifolds in my stock. See pic, I'm running a 318 with 10:0 comp and stock stroke. I did a zero deck with the KB 9:2 pistons. I run a windage tray and stock 318 heads that are decked with comp springs. I also run an MP fuel pump eccentric and did the galley oiling mod. My cam is a purple shaft 340 grind at .444 lift. I'm running 3.90 gears and a 2,500 RPM stall. Currently running an Eddy 650 carb. 20170430_154629.jpg Opinions? Keep in mind, I don't have a performer or any other intakes. Thanks fellas.
