Default TR55s or TR6s

Can NGK TR55s be gapped down to .035 on a H/C setup or do you recommend TR6s?

tr6's gapped .035 no problems mods in sig... my tuner said the gap just needs to be consistent. just check the gap and install. apparently the tr6's are better for modded vehicles to alow for more timing....just what ive heard.
