200 Exhaust manifold bolts

[60FALCON]

Hi,
Can someone verify for me the size and length of Exhaust manifold bolts for a 200? I believe they are 3/8" but length I do not know.

Thanks
chris

i would replace with grade 8 or stainless steel only. I am sick of those breaking off in the head.

And use anti-seize. And don't forget to occasionally put a wrench on them.

well stainless steel is brittle thats why most/all cars dont ship with SS other than maybe trim

money is a concern to a smaller degree
