Spark plug equivalents
I'm putting together a motor and the heads are some RHS Pro Torker vortecs. The sheet that comes with them recommends using ZEX #82070-8 spark plugs for street/strip use. Does anyone know where I can find a chart that shows what is an equivalent to this plug or can I just run the Autolite 605's like I use in my GM vortecs? The ZEX plugs a bit pricey.

http://sparkplugs.com
is a great site to look up plug info, they have a cross reff and an application chart, showing all the vehicles a plug will fit.

Re: Spark plug equivalents
That's a great website but I still want to know the difference, if any, between a RS14YC6 and a RS14YC plug? The RS14YC comes pregapped at .045. I'm wondering what other differences there are since a guy at autozone sold me a set of RS14YC's and he couldn't tell me the difference and I'm curious if they'll work in the 1997 vortec motor I'm running now.
