I was going to buy MRL myself until my racing buddy had a major failure with them. The roller fell off & destroyed a lobe on his cam. I'm using comp cams offset on both of my motors. Never had a failure that was related to the rollers.
MRL sells BAM Products lifters, which are manufactured by a former Crane engineer. It bothers me to hear about that failure, since I bought a set from MRL because they fit my lifter bores better (less clearance) than the COMP / IMM offset lifters I also have. This is the first failure of a BAM lifter I've heard about...
