Anyone wanna give me some assistance

Did my DOD Delete and after was getting slight misfire on former DOD cylinders
Did compression test all those cylinders at 160 psi and others at 200+ psi

Ls3 cam
LS7 lifters
Ls3 valley cover
Stock pushrods

Used an adjustable pushrods and swear I got a 190 psi reading but after installing a 7.350 pushrods I'm still getting low compression only on former DOD cylinder. Wet compression test is only 10+ psi
And did hear any major leaks on the valves with rockers removed to seal valves. My preload with those push rods is about 1.25 and with the adjustable ones set to 7.250 gave me a 3/4 turn preload but still low compression.

I Took out the pushrods and rockers cranked the engine for 15 seconds.
Loosely put the rockers and new 7.350 pushrods in and let sit a day.
Today I torqued it all down (on the base circle part of the love)
And checked compression 
#1 - 240 psi
#7 - 270 psi
#4 - 240 psi
#6 - 240 psi

​​​​​​Wow I quickly assembled it and ran it 
Sounded good, nice small baby lope at idle did sound like a leaking valve sputtering anymore.
​​​​​​Not sure if I'm out of the woods
Drove down the street pulled over did a crankshaft variation learn and let it idle a few seconds then shut off.
Upon start up there was chittering coming from the lifters rollers it sounded like. Car was shaking a but raised idle didn't help and shut off. Started up it chittered a second then stopped. Took it to work for a bath , let it idle sounded beautiful. Drove it some sounds good. Im stoked now.
I believe the lifter bleeding down did the trick because I've tried the adjustable pushrods with no success.

So do you think the issue was the pushrod length on the adj. pushrods was incorrect followed by some air in the lifters?
