Question HARD Start when hot

I own a 74' F-100 with a 390. It will start up in the morning when its cold just fine. after it runs for a while or i take it on a drive and turn it off it wont start again. The starter wont turn and it makes a terrible noise. The battery has enough juice but it seems like the starter is getting hot from the headers. That would be my guess. Has anyone had this type of problem and if so what can be done to fix it? Is it the starter or something else?

Also you can insulate the headers with some wrap. I have heard they also make a coating you can put on them like spray on kinda?

It does have a sheet metal cover but i have heard that it might be a Cut Rate starter. That could be part of the problem. Yea i thought about wrapping the headers, seems like a cheap and quick fix

My 390 with headers does the same thing. I have a heat blanket on my starter and it still only lasts 1 year or so, next time it's out I'll try to add a metal heat shield. Be sure to get a lifetime warranty starter, then it doesn't cost you anything the next time...

try getting a high torque starter. along with a heat shield or starter wrap. summit racing has one for a 390 made by PowerMaster. part number:PWM9506 for $199.95 and it's rated for motors up to 18:1 compression. and it has 200 ft/torque.
