Awesome! thx for the link. So can you just take off stock heads and throw on ls6 heads (higher compression) and not worry about bending or tapping valves? If it seems like i have no idea what im talking about its because i don't. THX

basically if you have a cam with a <235 duration and <.600 lift you will USUALLY be ok with ls1, ls6, 5.3, and afr's...as long as they are not milled...the t-rex is currently the biggest cam i know of that you can put in a car with unmilled ls1/ls6/afr heads...specs are 242/248 - .608/.612 - 110 lsa
