suggested items needed for chassis dyno tune

finally getting the time from work and have my rearend back together so i can knock this out, i moved from sea level in florida to NM which sits at 4300 MSL so i need to retune and figured a chassis dyno would probably be the best bang for the buck, here was my combo at sea level

557 11:1 cr on 93 octance gas, Aluminum BT heads, comp solid roller 254/260 @ .050 and .671/678, victor intake, pro systems 1150 dominator tuned by patrick at pro-systems for this motor 88 primary jets and 96 in the secondary's
34 total timing
autolite AR 3923 plugs

back at sea level i had mixed results as far as plugs were concerened the fron 2 seemed to run a little rich but the other 6 burned pretty good, no issues as far as pre-detonation running 34 on the timing

looking at running around 110 octane since i only bracket race this car now but wasn't sure on what i needed for extra parts to take with me or a suggested starting point for this altitude, as far as jet size and plugs etc., also looking at adding a jomar or the hvh spacer to help things out

thanks in advance for any advice/suggestions
