Why oh why. Sudden oil pressure drop.

Is it just me or do I read a lot of 440 Source stuff breaking or junk?
It is not just you. I blew a head gasket of theirs as well within 200 miles. This pickup they tout for stroker motors as it has clearance for the stroker. However, the clearanced area is where it broke. Maybe I tightened it too much and cracked it then??
