what spark plugs
 

i have vortec heads with 202 intake, sbc comp cams 292 501 lift cam. have autolite 25 plugs .just wanted to know if anyone has a different plug they use?

autolite 605 or ar103 depending part store autolite web site had a pdf file that gave plug heat range but it is hard to find every I try to use .

Huh?

I'd try some of the NGK racing plugs, they work great.
Go by any Napa auto parts store tell then what you have and what the intended purpose is and they will hook you up.
They run about $2 a pop, which is not bad for a racing plug.
Goodluck, Cp

punctuation is a good thing.

NGK or Nippondenso. Last longer and fire better than any american plug. Why do you think the Jap's cars get better mileage.

Hmm, cause they have smaller motors maybe?
1.8 liter vs 8.0 liter

Oh yea, i forgot about the cubic inches or centimeter thing.
