Timing is the normal issue here. once you get to 38 deg and depending on the amount of blowby at that point you will see valley pans blow up, I tried the pcv way even with 2 clear vents wouldnt blow oil out but still pushed the valley up , done this three times,, Finaly went to lean burn dist, set my timing at 34 , no more blowing up! some of those fine really nice looking dist can go way beyond 45deg total
