I'd always heard it called a finger lifter. Is anyone curently offering a higher ratio part? It seems to me that you'd need some sort of adapter to move the pivot. And between the high compression ratio and the VVT, it doesn't seem like you could add too much lift before the valves start interfacing with the pistons.
I am also curious about the porting you want to do to the TB. The only venturi effect I know of is the one that makes carbs work, but I can't figure out how it could help the LLT make more power.
I'm asking because I'm trying to decide which engine to get.
