I had these heads for a while with engine I rebuilt. Previous owner rebuilt the heads when the engine was built back in 2001. I rebuilt the engine back in 2003 to detune the engine from 12.5:1 CR to a more streetable 10.5:1 CR. Now I'm running Patriot Performance aluminum heads. Well I've decided to clean out my basement and garage and I found these still in the old Patriot Performance head box. Below are the pictures of the heads and what I remember about the specs.

Now for what I know about them:
Springs: Dual (beehive) style springs, not sure of the rates but heads were used with a .525 lift cam
Valves: One piece stainless steel, 2.02 intake, 1.6 exhaust
Ports: Ported and polished to hell and back, previous owner stated that he had spent $700 on a P&P job and it certainly looks that way.
Pushrod retainers, made my Moroso, are also installed.

Asking Price of $400 OBO. Heads are sold as is, I never ran them so I can't comment on the performance. However I can tell you that the car it was in, tubbed 1969 Camaro SS, ran a 11.7 @ 121mph in the quarter mile and had 507hp. You can contact me at
