317's or 806's??
 

Well, my 6.0 lq9 will be here on monday. And I about to make an order with TSP for a ms3 and some other goodies.

I have a blown 98 ls1 with 806's. The lq9 is coming with 317's.

Should I use the 317's or the 806's on the new motor?
I know 317's flow better, but compression would be lower.
So I'm kinda on the fence about which ones to use.

This is just a temporary solution till i get some cash saved up for some ported 5.3's or something.

So help me out guys....

crickets....

why not mill the 317s since they flow a hell of allot better than the 806s.

If I mill them, I'm afraid they will have ptv clearance issues...

put the ms3 in and check ptv, it will let you know how much you can take off the heads. even if you left them stock i would stick the 317 heads on because they flow allot better. you will still have good compression because the lq9 has flat top pistons.

alright...i'll do that.
Thanks.

just hold off on buying pushrods till you decide what your doing and measure.
