Neat camshaft, enjoyed seeing your pictures. Recall you wanted more than 112 LS and the lobe design was in the think tank. With special one-off heads you’re using, can understand your hesitance to add more radical lift, as it might require modifying the valve pocket (affecting optimum flow which you know works with those heads). Guessing you can’t wait to put the new cam in and compare stock tappet to your mushrooms, be nice to know that information.
You might also consider empirical test, set up the valve springs (using 185g) with 100 lbs on the seat, and turn cam over with a torque wrench (i.e. beam deflection/pointer style). You would then know different lift rate has between stock tappets and mushrooms right away (maybe none, maybe more). If it shows “much more” torque needed with the mushrooms, might make you think about your mushroom bushing's wear (for watching it). Excellent Andrew, positive progress : ) Alan
