Valve spring pressure

Did you check heads for installed spring height,to make sure your springs have that pressure and check springs to verify they are pressure they are supposed to be?
With cam & lifters broke in should be able to run around 140 seat and 375-390 open
without any problems. You don't have a hard surface lifter correct if you do you can crank
pressure on up.
You have some valve lash correct you need .003-.007 lash.
