ok i know this has been debated but the search was not working and i wanted to know. ok so i have a set of lq4 ported heads and a set of 5.3 heads. i am going with a cam that is 232 238 613 613 with a ls6 intake full exhaust with a good shot of nitrous. i know the lq4's will lower the compression a lil. and i know the 5.3's will raise it a lil. so which should i use??? oh should i go get the 5.3 heads ported too???

 

ttt because i need to know
