My .....with B1s and turbo, I'd be wanting pushrod oiling as well. Spraying the springs does provide oiling to the pushrod to some degree, but nothing like a dedicated oil thru pushrod or shaft pressurized oiling. I'd be more comfortable knowing the valve spring are staying cool with the spray bar, and the B1s are oiling the cups with pushrods or shafts.. B1s like and need the oiling in my opinion.
