Well, the math is simple enough for sure. Listed lift divided by ratio multiplied by new ratio.
For the small block, 1.7 is available for the Magnum head, special order for the LA head. So you could Equip an LA block with a Magnum head or TF and use 1.7 Magnum rockers on a LA engine or actually or better said with a LA cam activating the valves.
While getting the valves up as quick as possible is what I say all the time, there are limits. I just can say where they are. It’s to combination dependent. The limit being no actual gain in power.
