It is common to have temperature differences of 10 or even more between CPU cores for various reasons, manufacturing processes, which core is under the heaviest load at a particular time, TIM application between the CPU die and heat spreader (as applied by Intel during manufacturing process) and TIM application between heat spreader and cooler (as applied by user), cooler contact, or mount as it is sometimes refereed to.
A delid and relid process usually lowers overall temperatures but may or may not reduce temperature differences between cores depending on the cause
Delidding does eliminate your warranty on the processor so weigh your options carefully
