Can I use loctite on my header bolts with my aluminum heads, or would I be better off using antiseize?

antiseize isnt gonna help keep them in LOL. use some locking tab washers, or you can drill holes through the heads of the bolts and tie them together in pairs with thin stainless wire. thats actually the best route to go.

no dont use loctite

I've heard loctite works well to keep them in place...

but not on aluminum they probably wont ever come out, and if they do the threads will come out with them and then you ruined $1300 heads

just buy some locking header bolts, they're pretty cheap
and are the correct way to lock down header bolts

I used antiseize, no problems coming out when they need to and they're staying in fine

just buy locking header bolts, they have a washer that goes around the head to keep it from moving

on iron heads it probably wouldnt be a problem but never aluminum
