Hey Pete . . . really good technical information!

The modern Edelbrock heads all take .75" reach plugs (which is a good thing), but I've not seen older Edelbrock heads with .75 reach plugs (but they may have made them).

I currently have 3 sets of vintage Edelbrock heads (59x - center outlets) - none are designed for .75" plugs.

In the end, just measure the thread depth . . .
