We have just finished building our stroked 302 Windsor with 61309 Edelbrock/Chapman/Glidden heads. We tried fitting locally supplied NGK spark plugs but the hex part of the plug does not clear the alloy heads. The plugs cannot be fitted. Is there a narrower spark plug required for these heads or have I just been supplied the wrong plugs?
Appreciate your help.
