i have a 6.0 lq9 engine. im installing the solid roller lifters and i need to know if the oil hole on the lifter needs to face down towards the oil galley or up towards the intake.i would assume it should face down but i wanna make sure before i bolt the heads on. thanks for any info.

 

well you probably want to do more research but i dont believe it matters where you put the hole. the enitre lifter bore gets pressurized with oil. to be safe call the manufacturer of the lifters. thats what id do.
