Roller Cam LA360 Questions

I have found LA roller lifter bleed hole (looking from front of car) are orientated front to back, I believe Magnums are side to side. The LA rollers can bleed off sometimes after sitting for a while
causing lifter ticks until warm up. Lifters can be interchanged, keep Magnum lifter bleed hole
On the top side of engine, keep LA roller bleed hole on the higher side of the engine (measure engine with spirt level when on level ground
