I'm prety much redoing most of my under hood wiring and was wondering what's the best wat to go about running my ground wires. Engine and chassis what gauge should I go with, should I ground to the heads or block ( both are aluminum ), should I buy those braided grounding straps or is battery cable sufficient, is from battery to head and head to frame all I need or is there a better way? Please school me to the ways of the wise, thanks

I have the negative battery cable connected to the block, then a separate grounding wire from the battery itself to a ground on the firewall. I have the MSD harness ground connected to the same firewall ground. That is it.
Unlike some American made stuff my Japanese car does a good job of running two wires to every load. Saves me from having the spider web of ground wires I am sure someone is going to tell you that you need.

I'd go braided strap (because it's more flexible that a grounding cable) to the engine block if there isn't a clear path to the head (don't want chaffing to eventually sever the grounding strap) from the battery and use a grounding cable from the neg battery post to the frame. Just be sure that the braided strap to the engine has enough slack to accommodate any movement of the engine due to rotational torque while running.
Good Luck!
