These are 2.02/157 rev valves, gold double valve springs, flowed around 296. I have had the heads on my SS for 3k miles and just run a 13.46 at 97 with no power adder and 12.21 on 100 shot. They were special built for my Truck and don't have there valves and springs. Tuning and install can be done if you live close to north alabama. Also I can get you a custom cut cam to match your mods if you want. Price is $900 plus shipping.

 

They are Lq9 heads.
