Sbm x block

Gotcha. I think the guy talking about lifters above was saying or asking about having the link bars face the valley. With the 59* LBA they have to face the way yours do or otherwise the pushrods will hit the link bar. I thought that's what we were talking about.

I do believe one of the other poster was correct. When the resto block came out initially, the roller that comp had would not clear the block and the water jacket is close to the wall on those blocks so you could not grind without getting into the water jacket as some found out the hard way. Comp reworked there existing lifter to resolve the problem and comp confirmed to me that this lifter would clear the x block without grinding and clear the rest block.
