What plugs for Vortec heads???
i am going to get new plugs soon, and i have the 350 crate motor with the vortec heads. i know they take different plugs due to the heads, but im not sure which ones. i want to get some copper ones (autolites---or something of that nature), but not sure which part # to get. if anyone can help me out, it would be very nice.
PS, they are going to be coupled with Taylor 9mm wires and an Accell dist. -----> what should my gap be....stock or slightly more?

I use Champion RS12yc. I have another new set in my tool box
waiting. Going to be there a while 'cause the ones in the motor still look/perform as new after 2 yrs.
I gap mine at .035". Anywhere from .035 to .045" is good
with an HEI.
BumpaD82: I also made up a crossreferencechart for vortec
plugs,,, but your's is better ,.... Thats a keeper, thanks

Just use the stock heat range for now when you run NOS you'll need to change according to how big of "shot" HP wise..
