LSA/LS9 Heads on LS2?
I have been sitting on the side lines during all the L92/LS3 heads on LS2 engine threads. The GM Performance Parts catalog is now out for 2010 and I am seeing some good internet deals on LSA and LS9 heads. Has anyone put these heads on the LS2? The LSA heads are advertised as having "swirl wings" in the inlet ports. Anything special about these heads versus the LS3 heads?

Just spend the cash and get the the Trick Flow 215 or 225's. They are the BEST heads available for the LS2 hands down.

:iagree: Plus they retain their most their value even when used.

Its getting to the point where I'm agreeing with most posts. Soon I will be able to retire from posting.
Trick Flow rocks. |

:iagree: Spin you can't stop posting, I'm still on 101, but that's mostly because of you and your wisdom. Thanks. :thumbs::flag:

Too often cylinder heads are the secondary choice in the engine design process with the camshaft being the primary consideration. Doing so is a mistake and, in my opinion, the better approach is to commit to a power/performance level and then select the cylinder heads/intake that will provide the CFM to support that choice. Last, select a cam profile with valve events that allow the cylinder head operate efficiently and optimally. I'm not saying that a LS2, LS3, or LS7 architecture is better, just pointing out another opinion and another way to look at the options. |
I am also planning on installing Kooks headers and a Vararam CAI. The LS3 (or LSA) heads seem like an obvious upgrade since GM is basing all their new engines on this head architecture (square ports, big valves).
The Trick Flows seem like a lot of $$$ when I can get the LSA heads for a third of the price. Since the LS2 intake is garbage, I will need to get a new intake with either set of heads. |
WCCH LS3 heads are a little over $2k, they are some pretty nice LS3 heads. Or, you could buy the GM LS92/3 heads and let Spin or Charlie do their porting magic on the heads along with a LS3 intake. Yes, the TFS will require another intake, most likely the FAST. The built up and ported LS3 heads and intake will save you over $1000, or even more, over the TFSs and a FAST. However, the TFSs are built with serious strength and power, no real mods to do on a set of TFS 225s. The 1/3 priced LS3 heads you speak of I'm guessing are just stock and will require additional work to get them up to a porting and valvetrain standard of the TFSs. I guess it really depends on what your goals are and what you want to do with your engine. BTW, I just put over $1K into my lightly CNC'd L92/LS3 heads for: LS3 hollow stem valves, Comp 926 dual springs w/ TI retainers, and milling . . . I didn't go with the TFSs due to the additional $$$ I don't have as I already had the L92 heads. As you see, you can put a lot of money into the LS3 stock heads. Again, it comes down to $$$ and what your engine goals are. Hope this helps.

Did you get the head and cam kit for the LS2?

Charlie,
That is some awesome flow on your LS3 heads . . . nice, nice, nice, did I say that was nice. Also, super dyno! :thumbs: Mike C sends |

:thumbs::iagree:Brother you're in there . . . I just didn't have the $$ to go with TFS. They are awesome heads with some great torque and power. Like I said, if you try to get LS3 heads anywhere near the TFS standard, you will go over $2K. I already had the LS3 heads or I would have went with the TFS. I think somebody said you can take a mediocre set of heads and put the best cam ever in your engine and you will have a fair running engine, but if you take a great set of heads like TFS and put a mediocre cam, you will have a great running engine . . . just a paraphrase on what John Lingenfelter said and it does hold true. Heads and valvetrain do make a difference.:thumbs:

Yes, AFR and Trickflow are good at what they do but please don't knock GM engineering on this head - Ron Sperry, and I've known him a while, is really the genesis of this cylinder head line and without his input the other guys have zero to modify - and don't forget where the Corvette originates -
...again, not knocking you or any of us in the aftermarket industry but the comment here is out of line...

GM is not the end all for engineering. Trick flow or AFR has put loads and loads of R&D into making heads that are the best and worth the cash IMO.
