Looks to me like you will be fine , the springs are very similar & you are not doing a direct comparison , the seat pressure is different when closed but the spring is installed at .050 lower height on the Lunati Chart increasing the pressure # , the open load is also different as the Comp is tested @ .700 lift & the Lunati @ .600 lift . The coil bind # is almost identical also with .015 variance

That is a big relief to hear! Thank you again @Chryco Psycho
