I have a 91 rs with a 600 cfm edelbrock carb and rpm intake, headers and 3.42 rear. Stock tbi heads. I was wondering what do you guys think about it XE262h-110. Will my car lose to much bottom end. Im removing the rollers and putting in flat tappets(will i have problems or just remove and drop in new cam with flat lifters). Here are the specs.

.462 and .469 lift 218 224 dur and a lobe centerline of 110. What do you guys think.
