Rebuilt '70 455HO on eBay
 

Just ran across this rebuilt '70- 455 HO motor for sale on eBay. Got all the right parts and some great prep work on that deck. I'm sure it won't pose a head gasket problem at all. Could just be flash rust but it sure doesn't give a warm fuzzy feeling about the prep work. One can assume cleaned it up before he dropped the heads on, but I sure wouldn't have posted that pic.
