Need to know what to torque the plugs in at and what would be correct spacing, or even if someone can tell me how to figure it out so I learn myself. 383 w/906 heads

This is going to make some people here cringe, but given the plug / header spacing in my car (cars) I just carefully tighten the plugs down until I feel the plug washers "crush". Been working so far...

I just snug them down. Usually the gap the plugs need to be is on the info sticker in the engine bay.

 

Appreciate it dude
