<div dir="ltr"><div>I just finished the rebuild of my BN2 engine. I used Denis Welch lifters. They have the channel machined on the side of the lifter for better oil flow back to the pan. I would think these lifters would be hardened correctly.

What problems did you have pointing you to the lifters as the source of those problems? When I retorqued the head, I readjusted the rockers and found no problems.
