hey everybody new to the site. so I have come across a 2012 5.7 block from a 2500. I am stripping it down and rebuilding it. I happen to have a pair of heads from a 2003-2008 5.7. I have seen posts about putting newer heads on older blocks with different head gaskets but I need to know about the other way round old heads on new block. I know it seems silly since the new heads flow so much better but this is a budget build to Frankenstein a 5.7 hemi into my 1999 ford ranger.
any help you guys could offer would be greatly appreciated.
