In my opinion, the c.r. of 8.2 is a little light for the cam you have chosen, but if it were mine, I'd install Rhoads lifters on the cam. They'll bleed down at rpm's under 3,500 and take away about 10 degrees less effective duration. On the other side of 3,500, they'll pump back up and give you all the cam back.
