F/s 317 heads ported and 2.02 1.60 valves

**we_todd_did** · 12-04-2006, 02:46 PM

This is a set of freashly ported 317s, they have manly 2.02 intake and 1.6 exhaust valves, and have a 5 angle valve job, new seals and guides. They come with the linginfelter dual springs and titanuim retainers, these heads have never been ran and flow 320cfm at .600 lift. I have about 1300 invested, will take 850 shipped, or partial trade for 241s with upgraded springs, or I can keep my valvetrain and sell them a little cheaper. Also these have a 67cc chamber. I will have pics up Sunday night.
You can check my ebay or ls1tech feedback.

Wanna do a straight trade for some 5.3L heads with springs and valve work done?

What are 317 casting heads?

**we_todd_did** · 12-05-2006, 10:46 AM

6 liter heads same ports as the ls6 just has a larger combustion chamber.

Can you use 6.0 liter heads on a stock LS1?

**we_todd_did** · 12-05-2006, 11:11 AM

Yes they have better runner design which lets them flow more with smaller runners which makes the car more responsive and have more low end power.

What year were 317 casting heads used? Do you have pics?

**we_todd_did** · 12-05-2006, 04:13 PM

I know this is the most heard question, but why are you getting rid of the bigger heads for smaller ones?

If I put those on my stock LS1 would I have to change the cam to reap the full benefits of the larger head or could I stay with my stock cam?

Will those heads throw my computer off?

What kind of gains could be expected from those on stock, LS1 with stock cam? If you like email me at dedwards0950@aol.com
