Whiplash cams
That stock cam has a fair amount of duration and relatively lower lift, and that lower lift-to-duration ratio is a recipe for lower DCR with limited gain on breathing. And the 114 LSA keeps the overlap lower for a better idle in a production car, but that makes the intake closing angle later and that lowers DCR. The W/L moves the LSA a bunch narrower, which builds the DCR and low end torque up some but at the cost of greatly increased overlap and thus a poor idle (knarly in our circles! LOL) and poor economy.
In reality the 340/360 W/L should give you better torque and DCR than the cam you have. I can only guess at the intake closing angle, but based on the quickest common flat tappet ramp rates out there (like the Voodoo's), the intake closing angle is gonna be in the upper 50* range, so about 6-8 degrees earlier than the present cam. The lift is going to be higher as the W/L cam looks to have pretty high lift-to-duration ratios, so that might help top end some, depending on the heads and valves which may limit the usefulness of the high lift. But the narrow LSA and high overlap is gonna suck for economy.
IMHO, I would rather go with a slightly lower duration cam with a higher lift-to-duration ratio, like the VooDoo's or XE's. Something in those cam series' in the upper 258 advertised duration. Those will get you to the same intake closing angle as the W/L without the economy killing large overlap. The lift is the same as the cam you have (in the .440"-.460" range) Top end may be down a bit, so when you say you want a 'bit more', that lower duration may be moving in the wrong direction for you.
Depending on where you end up on lift and how hard you run it, larger lift cams push the valvetrain closer to floating. Plus the stock springs have limited lift before you get to too close to coil bind. The springs are gonna need to change to get any of the higher lift cams in, like the 340/360 W/L, and be sure to check the retainer clearance to the valve guide and stem seal.
And, of course, you could advance your present cam to get better low end torque. Do you know where the ICL was installed?
Ultimately, higher compression ratio is the best answer; you are in the same conundrum as the low CR of the 318. You can't get a bit more on the top end without hurting either low end torque or economy or both. The below is a good question:
So I guess the next question should be;
under what circumstances do you feel it is soggy?.
