will 317 heads work on my ls1 i just got my 2000 ws6 about a mounth ago right before i got deployed to afganistan and now im looking for a good heads and cam do yall think 317 heads will work on my car and if so what kind of cam will i need?
here is the info on the heads oh yeah and there only $250
The 317 heads are identical to LS6 heads, except that they have a larger combustion chamber. The heads can be safely milled to raise the compression ratio. Less than 27K miles on these heads. They are complete with yellow LS6 valve springs.

I would pass on the 317's unless you are going to go forced induction. You have to mill alot off to get back to stock compression. Then you run into piston to valve clearance problems. I would look for some 241's or 243/799's and work those heads. Search 317 heads in the internal engine section there are a bunch of threads about what it takes to get the compression up on a 346ci with 317's.

Agreed, unless you're going with boost I'd pass on them and keep an eye out for some used 243 or 799 casting heads. that's the LS6/LS2 head and they will perform better than your stock heads and the 317 castings!

oh ya 5 grand is plenty, especially if you do the work your self. If you have a shop put it together, h/c of course hardened pushrods and .600+ lift valve springs, then a dyno tune you are looking @ $3500-$4000. Labor prices can be ridiculous.

I ran 317s with my old budget setup... Worked perfect, car ran better ET/mph than most people would have guessed for the setup.
The 317s were milled .030 and hand ported, I would guarantee they worked better than most sponsors stage 1 ls6 head.
You can usually get heads milled for around 150$. You can find 317s for 200 or less if you search, you will have 350$ in a head that will perform better than a stock ls6 head (because of the raised compression) that costs 500$+.
I ran mine with a similar cam to the 228r... Mine was 226/228 .588 114
If you are going to go that route though let me know.. I sold the heads to a buddy of mine but he is going with a D1 so bought a stock set of 317s, he is selling the heads I had. My cam was specd to use with those heads in mind, so a 228R would work perfect.

But 243s are the only head that makes power
OP they will work fine, they will need some work obviously
