1985 K20 that I rebuilt 355 engine about 3 years ago & put on 1&5/8 Hooker headers. I am on my 3rd clutch slave cylinder. I am sure that the cause of problem is the driver side header that is too close to the line from the master cylinder(about one inch) and to the slave cylinder(1.5”). When I installed the new slave cylinder the Dot 3 fluid was almost black. I purchased some Titanium heat wrap and completely wrapped slave cylinder housing. Tried to wrap lower part of headers that is close to slave cylinder and fluid tubing but found it impossible to do with headers installed. What have fellow members done to solve this problem?
