SOLD!


I have a set of Ported 317 heads for sale. They were ported by Absolute Speed. They have a dual Crane spring in them, good for about .625 lift. The chambers are currently at 69.8cc

Asking $800 for them.

The flow specs are:

Lift: Intake: Exhast
.200: 150: 122
.300: 203: 171
.400: 253: 208
.450: 274: 217
.500: 292: 222
.550: 303: 228
.600: 310: 234

I just got the heads back from ET Heads. They went through them and made sure everything was ok. They cleaned them, replaced all the valve seals, did a clean up pass on the deck so the deck is perfect, and verified the springs are still holding good pressure.

These heads will be a great choice for anyone wanting to do a good head/cam swap and they are ready to be bolted on.

 

have they been angle milled or decked at all?

 

Stock is 72cc therefor the answer is. . . . slightly

 

ET did a cleanup pass on the deck which I believe was between .003" to .005"

 

Man, If I would not have just bought a set of 317's With WORN GUIDES from a fellow LS1 Tech member! Yet he said he didn't know??

I'd be all over these !

 

Are these LS1, LS6 or 5.3 heads? I don't think they are the 5.3 heads because of the combustion chamber is so big.

Thanks.

Bump.

 

They are LQ9 6.0L heads.
