Damn that is a good price!

 

yes,

that's the head im shooting for on my 6.0 ls2 HC .
im going to get them to 58CC and shoot for 12:1 compression
-

 

x2 hell yeah!

 

AI heads imo

 

damn... those ported ls2 heads do look tempting!

What would 65cc bump the compression to on an LQ9? is that just under 11:1?

 

should be about 10.8 to 10.7 id say since stock 243s are 64cc and they make a lq9 10.9.1 same as a ls2

 

Damn thats a really tempting price... How much power do you think these are worth on a LQ9? I currently have a TBSS intake and a Pat G EPS 222/226 w/ .600 lift on both ends. Is 50HP too much to expect over the stock 317's?

 

I don't know about 50 but you'll def notice a big differance

 

that's pretty damn close to what my Sierra's setup is, but my cam is a hair bigger.
I see in your sig it appears your headers have larger primaries than mine though... What TB are you using with the TBSS, a cable, or dbw?

now I'm wondering a bit about how these sdpc ls2 heads would effect PR length compared to stock 317 with 7.4's? Remain the same, or were they milled, or...?

 

I've got a set of Tsp stg 2.5 243's milled .020. Brand new, pm me if you're interested
