Can a tensioned bolt return to its original shape?
Thus, a bolt that is properly tensioned should be functioning in the elastic range (as viewed on the Diagram). If the load is removed and the fastener is still within the elastic range, the fastener will always return to its original shape. However, if the load applied causes the fastener to exceed its yield point, it enters the plastic range.

What should the clearance be on a flat top cylinder head?
Common dome designs include flat-top, domed, and dished. Keep squish clearance tight, usually .030″ to .040″, for a street engine with steel rods and aluminum cylinders. Also, eliminate any nooks and crannies creating dead spots for the air/fuel mixture.
