i have heard of people at higher altitude running higher comp ratios due the cylinder preasure not being so high but i think your better off going like everyone else says and staying around 10:1 or 10.5:1 max.
i have a street car with a stroked small block and aluminum heads, 10.2:1 compression and i run it on pump gas but i dont think i would go any higher for fear of burning something up.
