Advancing cam time moves the torque range down about 200 rpm for each degree and advancing moves the torque up about 200 rpm for each degree, roughly speaking. When I first bought my '93 LX back in the day, I installed the 1.7 rockers and retarded the cam time 4*. This allowed me to pull 4.10 gears through the 1/8th mile in 3rd gear. But for the labor involved, I believe it is more worth while to swap the cam rather than advancing the stock.
My personal preference is a long flat torque curve. The FRPP alphabet cams are proven and are still good grinds. And remember the XE270HR grind has about .544" of lift. Which may require fly cutting for piston clearance.
