Thx notlob, do you have any idea whether they can still be purchased new? My use would be on a modified SBC with non standard rockers and valve spring retainers, and Gil's Garage article is about Y-block Ford, and as I'm sure you know already, the valve/rocker arm/adjustment procedure is very different.
Also he is using it on a basically stock engine with a slower, smoother idle, with the engine running. The cam in my sbc is fairly radical and requires a somewhat fast idle. This, and the generous oiling of the top end on these engines makes dead engine adjustments with the "EOIC" technique on a cold engine much more practical.
Also, since the engine has aluminum heads, which expand more than the steel valve train components, the valve lash on a solid lifter alloy head engine will actually increase after the engine is completely up to normal temp. This requires that valve lash be tighter than specified for a hot engine if adjusted cold. Most use about .005" tighter. You can verify this with a quick check after a good warm up, again using the "EOIC" method on a dead engine.
