318 1/8 time improvement

What do you think about adding the magnum head? With that 1.6 rocker ratio I should get more lift and bigger valves are always good! Lol
It would be good. But, I always advise not to start unbolting and bolting a bunch of stuff - sort of throw things at a car without FIRST fixing what you have. Fix the bog, fix the traction, time it, tune it and play with shift points. You might get a 8.9 at 76 or something... just saying... then make your change.
