You know, I wonder exactly how much of a difference the faster rate makes in valvetrain wear, I mean, look at the roller motors. They seem to last as long as the slow rate flat tappet cams. Lt1 chevs are going 400K, no valvtrain issues on weak *** chevy gear.

I do believe everyone but comp slows the rate down on the last few degrees when the valve is closing to prevent premature wear tho.

Food for thought from someone who has put over 200K on engines in trucks with over 500 lift.
