What camshafts would be nice?

just another thing to throw in catcams are quite steep/wild compared to other so the ones you have listed will be equal to TRD 300 or so rather than 288... you have to compare the 0.1mm lift duration to tell the difference...
IMHO go with 7105149 it's a bit shorter in duration but still plenty of lift or if you want a bit less lift 148 (what I had planed but don't have the $$$$ for a stronger bottom end just yet)
and as the others said... springs and lifters are a must
TRD 90501-AE851 springs will work with the stock retainers and the lift or you can get a kit from Supertech incl. Titanium retainers...
for Lifters you can use Toyota 1SZ solid lifters but you'll need to measure everything out before ordering as they are single piece... or go for underbucket shim style like Toda or Arrowracing(not sure if they still exist).
Advantage of underbucket shims is you can just replace the shim if clearances change where as with the 1SZ you need to buy new lifters...

final note the 140 will take you up and maybe beyond 200hp so your bottom end realy needs to be up to the beating... and yeah balcktop ITBs are too big the lower air velocity too much which will result in less torque and power overall... you want to keep air speed flowing into the engine as high as possible (narrow ports) without restricting the volume (so as noarrow as possible but wide enough to support the power you are aiming for). set yourself a power/torque target before you start build.
