Cams or Final Drive
Hi guys, I'm debating on should I get a set of Cams + valve train, or should i pick up a set of Final Drive to install into my B18C5
Final Drive will be 4.785 JDM version into my USDM B16 tranny
and Cams will be something around Jun3...
Currently the head has milled for 0.25mm and a thin headgasket
any suggestion guys?

jun3 is a nice set of cams...makes great power similar to s2s2 at top end yet have stock idle characteristics due to similar itr primaries....4.785 FD is nice but i think it's a pain in the *** on the highway, especially with b16 tranny
edit: i forgot the answer the ultimate question in the post....cams>FD

FD just helps you with acceleration, making you reach the meat of the powerband faster.

If you track, FD is a nice upgrade. But if you were thinking of 4.7, might as well go 4.9.
Why go short when you get go shorter.

I would say FD.
Overall, short FD keeps your motor in powerband all the time.
Again, if your car is pure daily driver, do cams. You waste gas either way, but with cams, you can control your gas paddle. With FD, if you can live with driving 80 on highway, you are gonna be crusing at 4500+ all the time.

even with 4.9FD...yuo can't hit 4500+ rpm at 80km/hr=P...3200-3500 is more likely on 5th gear
also, i think jun3 will accelerate faster than 4.785 FD is because with an upgraded valvetrain, the overall powerband is increased. If the 4.785FD allows you to be in the meat of the power band (5-6k rpm), 4.4FD will be around 4.5k rpm with an upgraded power curve that might already surpassed the stock powerband at 5-6k rpm.
that's just my hypothesis, i'm not saying that it's correct. If any experts on here can shed some light on this issue please feel free because i would like to know too

I see your point Peter.
