Default need some input

I know this has been discussed a million times, I did do a search and read through a bunch of post. So now my question is I'm looking to put a cam in. Which would be better and would give more power between these two, or if you have any suggestion fill free to add your input. First cam is the Thunder racing blower cam 224/227 .563/.569 114 or the second cam which is 224/228 .581/588 114. The car still has stock heads, with LT's P1 with 8lbs of boost its an 01 also. A set of heads will be going on the car in about 6 months and I would rather go ahead and put in a cam that is going to work best with the heads so I don't have to change it again. Thanks

I think the cams are pretty close unless has older style lobes which would put it at a slight disadvantage.

I would say that neither of these cams has enough split on the duration. Should be 8-10 degrees for a blown application IMO. Also LS is too low, on a blown application it should be no lower than 115-117. If LS is too low, you will bleed off the boost as pressure is trying to be made in the cylinder. If you bleed if off you defeat the purpose of having the blower.
