No start 340

Just did a compression test and it’s not good #1, 110 #3, 132 #5, 122 #7, 105 #2, 120 #4, 120 #6, 105 #8, 130. Now what, valve lash is the one thing I haven’t checked. It’s a solid lifter cam I don’t have the cam card but the lift is around 575 any suggestions on cold valve lash?

if i didnt know at all, and was lashing cold, i would probably do 16. Thats more like 22 if the motor was hot.
22 is fairly middle of the road for a lot of flat tappet cams.
Wont put you far enough off to cause any issues i wouldn't think
