Chevy 350 grounding points on head

I have a chevy 350 crate engine and I'm trying to find the stock grounding points on the back of the heads to fix some electrical flickers.

Can someone show me a pix? The car is a clean frame street rod so I don't have a stock engine to work off of.

Any help would be greatly appreciated.

Any of the accessory bolt holes on the head will work.

What about the grounding point on the block?

if im not mistaken the only ground point other than the battery is off the head....Like Aperion said any accessory hole will do...the block and head are connected. From the factory it has a ground strap from the back of the passenger side head to the firewall.

That's what I keep hearing. I was just curious if anybody has a picture.

Stick your hand behind the drive or passenger side head. Any hole or stud on there can be used for a ground. It doesn't matter WHERE you ground on the head, only that you ground to the metal of the head and to the chassis.

Any particular spot on the head and block or any will do?

I'm having some trouble with grounding points and it's been traced back to bad grounds.

I'm going to make a grounding kit and just wanted to make sure where I should pull ground from.


Right now I have one wire going from each head's exhaust manifold nut to the strut tower. I don't have anything for the block.
