ok

I have lined them up in line with the recessed pad area off the plug hole

and I have lined them up with the open gap of plug facing the intake valve

need to know which way the shape of the of the cc on the heart shaped closed chamber heads swirl the intake charge around to to get it positioned in the right spot on the #302 heads, IMO

now I have also thought on putting the gap faceing into the cyl,so the gap faces the large side of the wedge to fire it from the small side and burn towards the big side maximizing the wedge effect of the wedge head

which IIRC is the right way for it to be facing

maybe someone else will correct me if I am wrong
