I get maybe a few tablespoons of oil out of the rocker vent over a race weekend
and have an unvented crankcase, so I really don't think the issue is inadequate
crankcase ventilation.
do you have an auxiliary line to your valve rockers that could be
over-supplying that area - still don't see why so much oil would be blown out
the cover vent unless there is another issue too.

Friends, I need some advice.
71 GT6 6 cyl vintage race car . At present running triple 40 mm Webers. After
two races last year and one test day last Friday on a rebuilt engine, we have
developed an oil leak at the head gasket on the left side of the engine.
After the test day I noticed the 1 qt filtered oil catch can plumbed from
rocker cover was full, indicating blow by ? Should I install a new head
gasket? more crank case ventilation? build another motor?
Thanks
