Aw man I wish I had seen this earlier 🙁I have a set of 400 head gaskets. Fel Pro. PM me your address and I'll ship them to you. You just pay the shipping.
Make sure you have the 400 balancer. I don't see the notch in yours in your pics but could be on the other side. 400s are external balance. A regular small block balancer will go on but that engine will likely get front bearing failure. They also have a weighted flex plate but your going with a standard trans.
