Just a couple more questions. I will have about 9.75:1 compression with my Vortec heads & I was wondering what would be a good recommendation for spark plugs? Also, does anyone know what to torque the intake bolts to with an Edelbrock intake to cast iron heads with the Felpro 1255 intake gasket?

Thanks guys!

I torque mine to 15ft/lbs. I've run AC Delco R44LTS, R45LTS6 and AR473. The AR473 are Autolite race plugs and I run these when I use the nitrous. I'd recommend the R44LTS plugs for you, good overall plug for street/strip.

If you want to find another plug, you need 14mm, .708" reach with a tapered seat.

Thanks for the info. What would you recommend for a gap? I have a Mallory Unilite & I was considering around .040 gap.

Thanks again.

I run mine at .035, which I think is the OEM plug gap. I'm running an MSD and have no problems getting these things to fire and burn correctly at that setting.
