Magnum 360 heads "best" for my build?

I am seriously leaning towards the 2.94 or 3.21 gears, converter stall TBD, purely from a fwy economy point of view. If I had an OD trans, 3.73 would be my choice ratio, but I do have those 3.91s ready to bolt in... tempting

I hear ya.

I could if I use SBC rockers. I have a set of stock vortec 1.5 SA stamped rockers off my 906 vortec heads... Hmmm...

What's the formula for figuring the difference in lift on 1.6 and 1.65 rockers? Doesn't seem like the extra .05 in ratio would raise the lift by .020".

Lift divided by rocker ratio mulitply new rocker ratio
For a Magnum head going to a 1.5 from a 1.6;
500 / 1.6 = 3.12 x's 1.5 = 468.75

An "LA" head going from 1.5 to 1.6 or "LA" head to Magnum head if you will;
500/1.5 = 333.333 X's 1.6 = .533.333
