oil drain back lines from heads....pics well I did what every road racer dreams of......set my heads up for oil return lines to deal with high RPM oil loading in the valve covers..... 
I drilled three holes (in each head) and taped them for 1/4" pipe (1/4" pipe to 6-AN line), machined a path along the edge, and prevented most of the oil from going back down the stock way (which includes over the crank).......the lines run down and "Y" into a 10AN block (the 3 6s to a 10) and run back into the pan above the oil level....
