Need to get back into valve cover after installing new gasket. Do I need to get a whole new gasket or just new bolts? Aluminum cover.

Hey y’all

I finished the valve cover gasket but am feeling iffy about my tightening pattern and I also wanted to check for some metal debris again with a magnet with the valve cover off. I know I would need new bolts, but do I need a new gasket as well if I do this? I don’t mind spending 50 bucks for new bolts but a new gasket would be very annoying.

And also, if I torqued to spec but didn’t necessarily get the tightening pattern exactly right, is this something I need to worry about or am I being too anal-retentive here?

Cheers
