So here’s my dilemma on my stock motor v8 32 roadster, the heads on the side that is closest to the firewall are showing a temperature noticeably higher than the head reads out on the side close to the water pump. I’ve read the stories of these motors being full off casting sand , rust , scaling etc .
So I went and picked up gallons of the evaporust .
The motor runs well aside from these elevated temps at the rear of the heads . My radiator seems to be working fine based on the temperatures it is reading at the top and bottom of the radiator .
Should I empty out the cooling system and then fill it with the evaporust ?
Is it similar to how guys are doing the vinegar treatment where they put it in then drive with it for a bit then flush and repeat the process.

Or is this likely to end up being a situation where the motor will have to be removed /torn apart to fix the problem? I figured if that’s the case the evaporust can’t hurt to give a try .
