I have a set of Sanford Racing ported and polished 853 casting heads with 3 angle valve job, comp 918s, titanium retainers, hardened seats, stock valve size. Heads have approx 9k mi on them. Made over 400rwhp and tq with these heads and a TR 224 cam full bolt-ons. I have no clue what the flow numbers or the combustion chambers sizes are. Heads are still on the car and she's hibernating for the winter so if I get a buyer then I'll pull em off.

edit: I'm going to go ahead and pull them off and take more pics of the bowls, cathedral ports, and exhaust ports.

Asking 600 + shipping



PM me for additional questions!

im interested, but chamber volume and flow numbers are pretty important details when trying to sell heads.

Sorry, but they were hand ported and polished by Mark Samford in Abilene, TX and I never had them flow bench tested.

853s were on the 97-00 LS1 cars. 241s were on some 00 and 01-02 LS1 cars. 243s were on the Ls6.

I'm not sure.... I would expect them to be a little bit bigger than stock 853s after the bowls were polished. I think 66.7cc is stock. Correct me if I'm wrong though.

Well their still on the car. This is a pic I took when I had to put a new intake gasket on a few months ago before I got my LS6 intake. It only shows the intake runners smoothed up. I'll just have to pull em off to get some pics up on here.
