Custom ground camshaft, low power

Here's the compression results. I tested cylinders 1,2,3, and 8. all were within 2 -3 of 150psi. All were tested with 4 plugs installed in the engine and 4 out. I propped the throttle all the way open but saw no real difference between that and closed when it came to psi. I connected the battery to my trucks battery while it was running so I could get it to crank strong and hard for all cylinders.
While I was at it I used a leakdown tester just to check things out. All 4 cylinders were in the 40-50% range. I cranked the engine over until I could feel the cylinder on the compression stroke and checked it at about half way up the cylinder at 80psi. Did I do anything wrong? or are my rings shot? I couldn't really notice any air coming out the carb or exhaust but I did notice a slight amout coming from the dipstick tube. Same story for all cylinders. Of course this is a much smaller hole than the carb or exhaust so it would be easier to notice. How nmuch is a normal amount? I know there will be some leakage past the rings. I have chrome moly rings and the whole motor has maybe 1000 miles on it tops. Is it possible the rings haven't broke in all the way yet?

Also, my vacuum at 800 rpm is at 10", 1200 rpm is at 14". Isn't this alot of vacuum for a 108* LSA cam? I'm not to concerned with keeping my vacuum up because I dont have power brakes or anything that runs off vacuum. Minus the gauge I guess.
