If I had a motor that was all together, and wanted to give myself the best chance of not having to grind on the block for link bar clearance, I’d use something like the Comp 8043’s.
These have the link bar located on the inboard/pushrod side of the “tower”.
There are probably a few suppliers of that style of lifter...... so pic your favorite.
I have no experience with magnum blocks at all...... so I can’t offer any advice with regards to the lifters for those.
I will say this.......... maybe I’ve been lucky, but I’ve had very few problems with flat tappet cams failing through the years.
The fact that you can’t get the roller lifters out of an LA motor if it has Edelbrock heads on it(without removing the heads) would def impact my decision on how I built it.
It would steer me towards a solid flat tappet cam.
