MII ride height and spring rates????

[Dgas56]

I have a 41 chevy tudor I am working on and it has a MII w tubular a-arms under it reputed to be a "Heidts", Now this thing sits LOOOOW,w a BBC and not much higher w a SBC (I replaced a complete 305/T350 w a 454/T350), I do not "think" it has lowering spindles. I do not have shocks in it yet (I am planning on MII GT V8 gas shocks) and see no provision for a sway bar or strut rods,
That said, What kind of a spring rates or length should I be getting w a semi heavy car like this to bring that front up a bit (2" maybe) ? and Where? I also need everything to run a steering shaft from the manual rack to the 59 chevy column.
YES ,I AM planning on 11" brakes,LOL.
