3/4" reach plugs in vortec heads?
So i bought this '87 iroc I have been working on it all week, guy who had it before did some hacky stuff. It has autolite 3924's in it which I know are a 3/4" reach gasket plug. I always used 104's in vortec heads which are the .708" tapered plug. Car seems to be running okay with them, should I put in 104s? Or are the 3924's okay?

I just use AC Delco R45LTS plugs. There's a random 6 at the end of the part number at parts places but they're the Vortec equivalent of the R45TS that everyone likes to use.

okay I know that.. what im asking is is using a .750" gasket plug in vortecs when it is supposed to take .708" tapered plug would cause problems or not..
