The exhaust temperatures at the point of exit from the body can easily get into the 800- 900 degrees F range with a stroked SB motor such as a 392.402 408 etc. If the timing is retarded just a little bit the exhaust temps rise under hard excelleration and will go way above those temps and these are all temps that can and will cause blistering so you need as much free space as you can get.
Check your timing often and replace that aluminum distributor hold down plate with a more reliable steel one so the timing stays true.
