d-series springs are small anyway...the inner spring on dual spring setus dont even really look like normal valve springs (at least the ones ive seen)

If you are willing to lose ~fifty thousandths of cam journal support area, then LS dual springs will drop right in.

Might as well take the LS valves with it. Or take the LS valves without it, and run the aftermarket springs meant for the ZC.

Strange thing is, the LS exhaust valve is 1.x mm larger than the ZC unit, and weighs significantly less.

If I was on a budget, I might still consider getting Supertech LS intake valves. Drops a bit of weight, and keeps things in the range of stockers or a bit less.
