anybody had problems with oil blowing out there valve cover breather and at high rpm (8500). prob. didnt start until new head was put on.i have done a leak down test on each cyl. and they hold . ive been told too try a pan evac. system . does anyone know the right way to do this . is it from the valve cover to the header or the crankcase to header?

you can buy a kit with a oneway valvethat keep exaust from goin into the crankcase and pulls air out. from jegs or summit that welds to your header and a hose goes to the valve cover.the only thing bad about this is it might suk all your oil out to the only engines ive seen these on were one that didnt run long i.e.drag engines wot for 10 sec.
