found a set of used ls2 heads off a 06 gto for 250.00 do you think this is a good deal?

how do these heads flow ported compared to ported ls6 heads?


Thanks

LS2 heads are the same 243 castings (same heads) as the LS6. Assuming that the heads are in good condition, they have good potential once ported. If you just swapped them with your LS1 heads and didn't change anything else, you wouldn't see much difference in performance.

for that price its a GREAT deal and you will show a noticable improvement..even if not ported..maybe not much put +20 at least.

Agreed, thats a very ggod price for the LS2 heads. The same head as a LS6 head except they have the regular solid stem valves instead of the hollow stem lightweight valves of the LS6s. You could see 15-20hp on a stock engine. One guy on the GTO website gained 29rwhp on a cam and bolt-on LS1 GTO.

just looked at the ad again and they are not off a 6.0 gto. they are the 317 casting.

price lowered to 175

Yeah, I just sold two sets for $425.00 each. You can buy them from$375.00-$450.00 usually. Good cheap alternative to ported heads for a few hp.

Note, the 317 casting has the same improved port design as the 243, but the combustion chamber is 71/72 cc for the 6.0 truck with 9.5:1 CR.
