I just installed my 243 heads, and I attached all 3 ground on the drivers side to the inner and upper bolt hole on the back of the head... just read that 2 ground go to one bolt, and one goes to another. Am I ok?

Also, I forgot to bolt down the knock sensor bracket to the back of the head. Will I have access to do it with the head bolted down?

Thanks guys!

 

As long as all the surfaces were clean and there was good contact, I'd say you will be fine with the ground. As long as the intake manifold is not on yet, you should be able to reach those bolts anyways, although its tough

 

Grounds should be good to go. they are both bolted to the same head, so it shouldnt matter which bolt they go to.

 

I have all the grounds to one bolt hole and its fine.

 

Great, thanks guys!
