340 exhaust manifolds 2863553 and 2863549

Ok folks I was going thru my storage shed and found these. Not sure where or when I acquired them as everything I've dealt with over the years have been big blocks. 340 exhaust manifolds castings 2863553 and 2863549. The heat riser is gone. Looks like someone put bolts in shaft holes. Doesn't appear to be welded. Look at pictures and see what you think. Located Blanchester Ohio 45107. Looking to get $375.00 plus shipping or willing to meet within reasonable distance. Please keep in mind I am working 6 days a week12 hours a day so may take a few days to get boxed and shipped. Prefer cash if picked up or usps money order. Also there are no visible cracks. I can only upload the one picture. If you want more, fire me a pm with your email and I will email more.
