Questions / comments:
1. What did Dwayne P. suggest? And are you second-guessing him?

2. I'd be hesitant to run MM-type lobes w/o both EDM lifters AND nitriding... and I'm not so sure they'd be the right choice for an engine getting a lot of street miles. Something milder will be kinder to your valve springs, etc., over time.





The motor will respond nicely to faster ramps. It is just a trade off on valve train abuse and running closer to the edge. There are several profiles between the XE and MM profiles in aggressiveness, but most are recommended to have direct face oiling and nitriding.
