Is it need for breslin splict lock fasteners? If I do ever take off the header bolts, I let the car come up to temp, and then cool a little before I break them loose, to avoid stripping the threads. Regardless is anti sieze needed?

 

Not necessary, but it is definitely a good idea.

 

I have a general rule, anytime you thread dissimular metals together (steel bolt into alum head) you should use anti seize.

 

I use it on my Stage 8s
