A company called LS1 Source who are no longer in business. I don't have any flow numbers. They came on my heads and cam Firebird Formula when I bought it. Just had them freshened up.

I know the best ET in the Florida heat was 11.85 with 3:73s in a 10 bolt and a 3200 converter. I also have the cam. It's a custom grind Lunati 112+4. Single springs. Don't know the brand. Stock size valves. 59cc heads.

I can sell you the heads and cam as a package. Please let me know. Thanks.
