I though about the rotation of the lifter aswell, being off centered. The size of the small lifter bottom will be too small to still rotate, but since the cam lobe is quite a bit smaller then the stock lifter I figured you could get away with a bit smaller lifter bottom.
When going to even smaller lifter bottoms (like on my figures) you need to make the cam lobe narrower, or at least grind one side of it away, so you'd still get the rotation of the lifters. Dunno wether that would still be realistic tho.
About the roller lifters, I think it will be worth looking into. They will most likely indeed be heavier then stock lifters but since there is less friction you could get away with more radical profiles without putting too much side load in the lifter. Hmm, interesting!
But how do these ones below work? Is there a slot in that connection piece to allow for the side to side movement, neccesary since both lifter dont move simultaiously?
Actually, JohnMc, maybe you are willing to try some of this? I mean, you have to take of the head of that engine in your 544 anyway... ;^)
Cheers, ben
