Re: 289cfm lt1 heads
I'm not sure on the cc's of the heads, i just got them on this board and i need the money so i gotta sell them. i know they made 400 rwhp n/a and 622 with a 200 shot. if you have anymore question let me know i'll try an answer them for you.

My understanding is that these came from xxsaint69x's 383 Stroker motor. His post in the FS section lists the cam size too. These are awesome heads for a great price, but I am going to pass for now since I am already in another deal.
