if the trick flow package isnt good for the money on a LT1 engine, then...what would be the best heads i could use with a cc503 cam. thanks

 

You need to put down more info to get any real help on this. What is the build on your motor, and mods are on the car. The Trickflow heads are great if you do a 383 or bigger motor or use forced induction. If you are using a stock motor or a small displacement build have your factory heads ported and talk to the porter first about your plans and cam selection.
