Is there anything special you need to do when changing to the big block heater core because when I put the tall valve covers on my engine, it hit the one pipe of the heater core and wound up cracking it? Now I'm not running one because I can't fit a sb one in with my valve covers and it really shortens my driving season here in north east Pa without heat.
