What kind of spark plugs does everyone prefer?

Sounds like NGK's are the most used or will use next time on this chat board!  Any ideas on the number of the NGK spark plug I'd need for a 68 383-4? 
Thanks

I'm assuming you're using the factory heads....if so, the NGK XR5 is what i would use on that engine.

Thanks Ron, As far as I know they're the factory heads!  Just went surfing  & stumbled across this web site (NGK) that looks at spark plug part number info & it has a huge cross reference to many other manufacturers of plugs.  It's worth a look if you want to compare, the web site is  http://home.att.net/~ngkaz/wsb/html/view.cgi-home.html-.html

Thanks again.
