Head bolt thread sealant question

OK I installed my AFR 180 heads Saturday. I used new bolts with permatex thread sealant. For whatever reason, this morning I wasn't sure I torqued the bolts correctly so I broke the bolts loose and retorqued them. My question is should I have reapplied the thread sealant or do you think I will be ok?

Should be fine. I've done it with no issues and for good measure I run a sealant in The radiator. GM caddy pills or bars leaks.

I think it'll be fine. You'd be more likely to stretch those bolts and run into issues that way if you keep re-torqing them.
