Long Rod 800 compression??

[BILTIT]

Anyone have some compression numbers for a long rod 800? I have Indy specialties LR and was running a 12.5 par head at 2200' but didn't check the compression. I am swapping to 13.6 domes and will check compression but wanted to compare. Curious what the difference would be at 6-8k'?

Mine is at 107 at just Under 6000 in Denver

Only have 73 miles on mine. I will try to check tonight or tomorrow and post back. 2700' here

145psi at 2200' with 13.6 domes. Engine/ambient temp 50f (in my shop).

Gained 250 rpm on top with the new domes, need to add more weight (67.7g before, will max out my adjustables at 69.5 and try it). Pulls nice and strong.
