what spark plugs for my vortec build?
I'm wondering what you guys recommend for a good vortec head spark plug. I know they need to be .708 reach but what about temp ranges and gap? I have a 355 with dished pistons, .045 quench, 59cc chamber, and about 10:1 compression. This is my daily driver too.. Any help is appreciated

Autolite 104 or NGK TR55.
Those are regular copper plugs.
If you want platinums, someone else will have to help you. I run my stuff hard, so I don't use them.
Edit: Assuming your ignition system is up to OEM standards, run an .045" gap
