How can you make a specific recommendation when we don't even know which engine he has yet? The 340 cam is a big big for a 318 if that's what it is, but as usual, we don't have all the information.
Nevermind, I saw the very last sentence. So it is a 318. So the 340 cam is a bit big for it, IMO. Something like trailbeast is talking about might work well, but his cam is a hydraulic roller, so that's comparing apples to oranges.
