Hey guys, I need to decide on plugs for my build. I have a 440 that's .030 over running 10.6-1 compression with the 452 MP aluminum heads and a 480/490 lift cam ground to dwayne porter specs. Also running HP manifolds. Nothing fancy just trying to bump power a little for an auto and a/c car. What plugs do you guys recommend????
Thanks in advance
