valve train geometry, angle of rockers relative to valves, affected by new parts Options

[Tking327]

Good Morning. Doing rebuild of my '70 1.7L. new parts include pistons, jugs, cam, and had new valves, valve guides and seals and springs installed and seats ground. For cost reasons I decided to re-use original pushrods (in good condition) and rocker assemblies. Upon adjusting valve lash i found there was a larger than expected gap between the tip of valve adjusting screw and the top of the new valve (visually about 3/16 inch gap, at TDC, uniformly on each cylinder). I nevertheless the adjusted the screws to 0.006 according to normal procedure (there was plenty of thread) but now worried that my geometry is off and i may get damage at startup, or poor performance. Visually, after adjustment, i would say the angle between rocker arm and top of valve stem is about 85-88 degrees but thats hard to eyeball. Am i crazy to move forward without custom fitting/ordering new pushrods to make up the gap? Why do I have such a large gap given the new parts are stock from reputable suppliers? I waited 7 months for my cam to be made - i am getting impatient and dont want getting new custom length pushrods to delay me by more months - but at the same time want to protect my huge time investment and have it run well
