Comes with springs, retainers etc. No rocker arms included. The only thing I cannot find at the moment are the rocker stands (GM Part number 12600936). I think I know where they are and i'll include them if I find them. Otherwise, they are $10 each or less.
I used these heads for a Ysi build and made 825rwhp at 17lbs with ZERO signs of head lift.
They require a minimum of a 4.00 bore.
Flow data on 4.155 bore.
I asked Richard at WCCH what the difference in flow would be from the tested 4.155 bore to my 4.070 bore and he said it was minimal.
1600 shipped/insured.
SOLD

As a matter of fact I do have the receipt. I am at work and it is at home. I can send it to you if you want to provide me an email address.
These were originally Stage 2 heads sent in for Stage 3. The receipt (which is in my name) for the stage 3 work specifies they were formerly stage 2 heads.
The springs are PRC EHT springs but I cannot remember if they are .650 or .675 lift.
