We just finished the new 5.3 CNC program this week, with a Ferrea 2.02 valve and minimal hand finish work it flowed 317 @ .600", and flows better everywhere then the old port, or just about anything else we have ever seen. I will shoot you a PM.

Hey Brian, I'm really interested in the new version of your 5.3L heads as well. Can you send me a pm about them? What I really want to see is how much they gain with hand finishing to comp level. Can you get a flow chart from a set of hand finished heads soon?

For me, these are going on a regular LS1 (not a stroker like the poster above) and I have stock pistons without reliefs, etc.

Hit me up with some info if possible. Thanks!
