You see, the installed height of the valve may change but the rocker assembly can not push the valve ANY close to the piston than the calculated amount of lift unless there is a problem with the pivot point being higher than it should, rocker arm ration has changed, or valve stem length has changed.


I agree to a point. The problem comes in there of the lash adjusters. If the seat isn't cut deep enough, the installed height of the valve is lower into the cylinder. The lash adjuster will compensate for some of that by pumping up more, ending up with the cam still having the same lift on that valve (meaning....a .400 lift on a valve that's already .050 deep ends up with the valve in an effective cylinder position of .450, not .400 where it should be). The valve stems were measured and no discernable difference was found.

I agree, but we'll check them anyway.

As far as deck height, with the head sitting on a flat inspection surface, we put a height gauge on the valve cover mounting surface. We saw maybe a .002 variance from end to end.

And yes, these heads were from Kinger. I had the 3L valves installed so they should have installed new exhaust seats and cut.....cut existing intake seats.

I'll put holes in him!!
