Guest Posted December 3, 2000 Share Posted December 3, 2000 I'm porting some '70 455 heads. There is a semicircular lump of material in each of the combustion chambers below the plugs. Does it have a purpose, or can it be removed? Seems to me it is just an obstruction to the flame front and a small hinderance to swirl. What say ye?
