take your time

it usually doesn't snap, for me at least, and i've taken my manifold off about 4 times already. Stock engine, 91 status, didn't break anything the first time.

When you put em back, antiseize if you want

If you can, keep going, but if not you at least have the initial bond broke. I've always had good luck with them being warm as it helps expand the threads a little, making it easier to remove. The PBlaster helps too as it penetrates/eats rust to a degree.

Doing it cold can work, but I've broken way to many studs when I was younger on 5.0's to risk it on anything again, especially one with aluminum heads.

thanks for the tips fellas

looks like i got my weekend project cut out for me
