David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting

With the 10:1 CR, it shouldn't need as much spark lead as a factory build.
And that's on top of the possibility that the heads actually help create a more homgenous mixing even at low rpm.
I think its going to need high test (93 anti-knock) on the street unless the cam is such that it bleeds some of the compression off. That's stuff that's above my pay grade.
