Hi all, haven't posted for awhile, been here almost everyday though, been finishing my new garage. I purchased a modified head, copper head gasket and mushroom lifters from Quenton earlyer this year and i'm almost ready to install them. My question is can anyone provide a step by step guide on how to adjust the lifter clearance on an 07 NE5. I know what the clearances need to be for my upgrades, I would just like a detailed how to. Did a search and came up empty.
