I can't answer the first question very well - I can say that you CAN get that power easily w/ flat tappets. As far as adjustment, I don't think it's ever "constant" - but more than the hydro roller...

I can answer the second one. 2 bolt mains are fine for 350HP. They say the 2-bolt mains are good to 550.

If it breaks, don't come looking for me. I have 2 bolt mains and am running fairly significant horsepower. So far, so good.
