New heads

[76Charlie]

Alright, I have peanut port headed 454 .30 flat tops with valve reliefs with 800 cfm edelbrock carb with edelbrock 2162 camshaft (218/228 @.50 with 114 lsa and .500 lift) with stock exhaust manifolds My motor is choked big time, I know so. I plan on getting some 100cc edelbrock heads to bump compression from 7:8:1 to 9:1 and of course headers. My question is that with this increase in breathing as well as compression will the EDL 2162 be sufficient? Right now the motor is sluggish, and well, I just know it feels choked up and plugged because of the peanut heads. While I have the motor apart should I go ahead and get a cam more along the lines of (221/231 @.50 with 112 lsa and .533 lift) I don't want to run the risk of too high lift with a new head and smashing a valve, I don't know how far from stock ration I can go before that becomes a problem.
