Funny you mention chevelles.com as I am a member there. They love 496 builds over there and that is what I am building. AFR and Brodix seem to be the preffered heads. I got a set of edlebrock RPM heads cheap so that is what I am going with. Big blocks are prone to valve float that is why solid cams are recomended for anything more than a mild street motor. I will be using a flat tappet cam for now because the cost of rollers are a little out of my budget for now. Even so my motor is very straight forward and should make 650 horsepower. Guys running brodix or afr heads running solid rollers are making 700+ horsepower with ease. As much as LS motors are touted around here it is all too easy to blow them away with a big block.
