Need New Head for my '85 22re 4 Runner

I second that for thorley. Mines gotta be 20 years old now and still working well!

A tri-y design has more midrange torque than a 4 into 1 design, where most of its power is at the top end. The thorley would work very well with that cam.
 
Thorley is the way to go. Whether or not it's worth it is another bucket of fish though - it'll make a noticeable difference, especially with your new head, but not $500 of difference IMO. I wouldn't drop the coin for a new one, but maybe you've got more money than I.
