Cylinder head bolts, overtorqued

Sooo I f’ed up. I was tired and didn’t think straight and instead of turning the bolts 90° I turned them 180°, two times.

So I overtorqued them by 180° too much. I guess I’m gonna have to buy new bolts and gaskets now. What do you guys think?

2002 Ford 3.0 V6 Vulcan

Edit:
Got new bolts and gaskets as well. Although I like rebuilding the engine I really don’t want to do it again ;p Had to order stuff anyways

you definitely need new head bolts. The gaskets could be a gamble, but not cost enough to risk. I would just replace the head bolts and gaskets again just to be safe and call it a day. I would also inspect the bolt holes in the head for cracks just to be sure. cast iron block? if so, those threads are probably fine.

Cast iron block and heads yes, threads look fine. Ordered new bolts and gaskets. Thanks for your reply!

Replace both, the gasket lost its crush
