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

EXACTLY. If someone comes to me and says they want to build a 318 and port some 302 heads I will tell them to get their head screwed on straight and use a set of 360 head and leave the grinder alone.

Unless you are Running Super Stock or Stock eliminator you leave those castings alone.

Unless you like wasting your time behind a grinder to end up with less than if you started with a better casting.

It’s just stupid using those heads.
Only build I could kind of see them on is a 273 but even then probably still worth going 360 like 66fs does.
