I have a set of Patriot Performance 5.7 Stage II Heads for sale. Only have 12,000 miles on them. Heads are on my 98 Z28 It is street driven. Never raced. These heads are in excellent condition.

I am upgading to a 416 stroker and LQ9 Stage III Patriot heads.

Taking heads off tonight and I will send pics to anyone interested.

$700.00 + shipping.

 

Do them are LS6 type (chamber size??) or 317 (72cc chamber size)?

 

what springs?

 

Are these Ls6 style heads?

Got any flow numbers?

 

hey man pm or email head pic evwhereru2@aol

 

These heads have 66cc chambers. They have 2.02 Intake Valves and 1.57 Exhaust Valves. Patriot Gold Dual Springs. I made 386 rwhp with an A4 unlocked. I have not dynoed the car since I put the 6 speed in, but the guy who tuned it thought it would go 400+ with the 6 speed

I am at work now, but when I get home, I am going to clean them and take some pictures.

 

none of these are showing a 66 cc chamber? Are these custom chamber size?
