No, the 85 and 86 are short reach gasketed plugs used on B/RB engines and also on my 318 Poly engine. Threads are approximately 3/8" long.

Look up a 340 plug to get the difference. They have thread length of approximately 3/4", thus are called long reach plugs.

BTW, long reach plugs are much easier to find at your local Walmart than short reach gasketed plugs. For years they were all one would find in an aluminum head.
