I have a set of Edelbrock RPM heads on my SBC 400 engine and I was changing the sparkplugs on them and when I got to the number 8 plug which I removed with no problem and when I try to insert the new plug in the head it is going in crooked not straight like it suppose to go,the plug will not even go in all the way,I have changed the plugs on these heads plenty of times without this problem can the threads be damaged and will the head have to be removed and be a machine shop job?THANKS :cry: :cry: :cry: :cry:

First try a spark plug tap. I was able to clean up bad threads on an aluminum head using a spark plug tap.
No, the head can remain on. The tap I have has 2 sizes and looks just like this one. You should be able to get it just about anywhere.

Okay cool,so it just screws in and makes new threads and just back it out,I see some on EBAY but will try near by auto parts stores first.THANKS
Dumb question, but has nabbed me a time or two - are you sure the spark plug washer hasn't come loose and wedged itself in the opening at an angle?
The tap shouldn't make new threads, it should find the original and fix them. You will need to be sure it is inserted straight.
"The plugs Im using dont have washers."
That could be what caused the problem. They should be gasket-seat plugs, not old tapered-seat plugs. Autolite 3924 or equivalent.
