I had burnt my intake once, but when I redid the heads(hardened exhaust seats) I blocked off the heads so that the hot exhaust could not travel thru the intake. That being said I disconnected the manifold heat control valve spring.
I also run with the choke wide open all the time.
Since the hot exhaust cannot go up thru the intake manifold, the paint still looks great.
If you don't block it off, there is no paint that will withstand exhaust heat.
