I recently placed a dodge 440 in my 715. Just today I started it and let it run for 10 min at 2000 rpm for the first time. But while it was running I noticed that the 2 rear cylinders on the passenger side were running a lot hotter (they were cooking the ceramic coating off my headers) so I shut it off. Does anyone have any idea might be going on? Right now I am running open headers, which makes it really hard to hear any strange noises, but I thought I could hear a slight squeal on the passenger side, I was wondering if it weren't just the rocker arms hadn't gotten enough oil yet (even thought I primed the oil several times) or what was going on. So if anyone has any ideas, I would appreciate the input.
