No, 10lbs or so isn’t likely going to fix it.
40-50 is more like what it will take.

The other issue is trying to find something where the distance to coil bind is within the desired range.

Something like an Isky 8205-SP or 8205-Plus, and then adjust the IH to 1.900(-.050 locks).

More than likely, you could just do the intakes.
The slower lobe, 1.5 rockers, and lighter ex valves probably aren’t having any problems.
