Here's the situation. 71 Satellite Sebring, 340 with Hedman shorty headers. I've had headers like these on the car for over 8 years. Since I've installed a new pair of the headers the engine mounts have been melting. The mounts lose their form, compress, and my engine drops a 1/2 inch. I've gone through 3 sets in the past year.

I'm using the Schumacher Creative interlocking mounts and they've been great about warranty replacements. I'm not sure if those mounts use a softer compound or what.

I don't think a heat shield is practical, given the space I have to work with.

I'm thinking of the following options:
- Trying stock rubber mounts and seeing if they last
- Going with solid mounts and dealing with the vibration

Has anyone had a similar problem? Has anyone run solid mounts on a street car? I don't want my teeth to fall out driving this thing.

Any advice?

Thanks.
