Just wondering what plug wires/boots people like with their Try-Y headers in a big block A-body. Some tubes are pretty close to the plug. What brand and combination of 90, 180, and possibly 135 degree boots have worked for you?
The only wire ends I’ve seen survive that stuff is the wires with ceramic boots.
They’ll take the heat BUT they can be fragile so you have to show some level of soft hands when screwing around with them. Especially if they are pretty warm.
I saw my cousin break not one but two of his because his butter fingers couldn’t hold on to them.
You can get them in Mallory (red only) or Accel (black only AFAIK) and maybe MSD but I forget if they have them or not.
