Starting with checking springs and a dial ind. is a good start, but then I like to use clay on all 8 pistons with the correct springs.
This summer, I had 040 on intake with a thinner gasket of 051 because I didnīt want to test with the new cometics that are 060.
This was with lash and checking springs.
Do a check with clay and correct springs.
Exhaust needs more, when the piston is chasing the closing exhaust valve, and not the other way around( intake chasing piston down).
Any flex in cam, cam drive and valve train will benefit the intake clearance.
