You will get a very little noticeable seat of the pants feel from them. Your time slip will tell you the difference. You will gain a little more duration out of your cam with them and of course you will gain the lift. Make sure you springs/heads can handle the extra lift.

typically u gain .5 degrees duration per .1 increase in ratio on rockers just beware that your valve pockets may not have the needed clearance for your valves w the increased lift
