Bill,
	It sounds like you must have massive valve reliefs in the pistons,
.190" is a bunch.

	With .475" of lobe lift the valve lift with a standard 1.5 ratio
rocker would be roughly .712", which will bind most all springs except those
made specifically for the higher-lift cams.  Most springs set up around
1.900" installed height IIRC, and the last ones I used showed bind at
1.200".  If the installed height is short, obviously you have less room to
play with.

	Curious that you're only seeing it one one side.  What were the
installed heights on the springs - is it possible that the driver's side
head has a taller installed height?  It makes me think that there may be
something else at play here, but if coil bind is definately occuring, it's
pretty cut and dried.

Steven
I check piston to valve clearances and have 190 thousandths so that is no
problem.
I have 2.14 intakes and 1.81 exhaust valves with dual springs.
The Spring coils are bottoming out so I am suspecting too much lift on the
cam lobes.
I checked the lobes at their highest point and am getting a reading of .470
to .475 lift. 
I have rotated the crank by hand and watched as the lifter comes towards the
top of the lobe.....pop, there goes the push rod. I am now using the push
rods out of my old poly 318 so I don't bend any more of my crower push rods.
Takes most of the adjuster screw but they still work.
It is happening on the 2 - 4- 6 and 8 banks not the 1 - 3 - 5 and 7 banks.
That is what is making this such a head scratcher.
Later
Bill
