I experienced a problem with valve springs in the assembly of my 1296 engine.

With the head work that went on, the valve seats ended up higher in the head 
and therefore the springs would not install with the
correct pressure.

The fix was two-fold.  First, Ted Schumacher provided some Iskenderian Springs 
and we had to install them with spacers underneath to
achieve the proper spring rate.
