ASSUMPTION: 310 cam is 310 degrees duration? Not knowing the 3T as well as I know the 4A... it is likely you will need a few thousand dollars worth of supporting parts, and machine work to properly run a 310 duration cam.

If you are prepared for that kind of expense, I'd say new pistons at the very least, and headwork would be advised to "get all you can" from the cam

I was told to shaved the block at 40 and the head at 40 as well and to leave the cylinders stock that way the engine won`t
over heat! and to get a set of double springs.. does it sound right to you?

40, and 40 is .080", or over 2mm. Just cutting, without knowing isn't the best way to build an engine. Yes a cut of the block to get the piston closer to the head, and cutting the head shrinks the volume of the chamber... BUT neither of these take into account other changes they cause... cutting the head and block 2mm may cause rocker, or pushrod issues. Double springs may also cause pushrod issues. As I said I'm far more familiar with the DOHC "A" engines... but I do know that quality machining, and careful assembly are paramount to a good build.
