Default MTI stage 3 heads (243/ls6)

Exactly as the title states...
The stage 2 MTI heads are $2,850 + an exchange from MTI.
The stage 3 MTI heads are an additional $595 from MTI.

From MTI these come with MTI springs.
I have upgraded these springs to Patriot Dual Valve Springs(.650 lift).
The heads have brand new valve seals, valve liners, and a competition valve job all done by LME(out of Houston) just a few months ago.
I am pretty sure that the heads already have the larger valves as well.
Feel free to call LME and confirm, or I can provide a receipt.
The heads are still on the car, but will be removed when my new big $$$ heads arrive.
These heads flowed 338cfm @.600 and put down 515rwhp through my old combo.
I am located in DFW, TX.

Asking $1,800obo plus shipping, but would prefer a local sale.



Here are the specs...
MTI Stage 3 Cylinder Heads:
The Stage 3 is an upgrade based on the Stage 2R heads. Stage 3 heads are intended for larger displacement engines with non-factory cylinder bore diameters (over-bored or re-sleeved LS2s including the C5R block). The Stage 3 upgrade involves enlarging and polishing the combustion chambers to match the required bore diameter, as well as having the option to replace the 2.055" intake valves with larger 2.080" custom valves. This Stage 3 upgrade is only available at this price upon original order placement of MTI Stage 2R cylinder heads.

Was the 515RWHP on your 427?

Yes it was, through an auto.

Thank you.
Yes, they are one of the best set of heads on the market.
I am also willing to work with someone on the price.

Thanks again.
Yea a few PM's here and there, but nothing set in stone.
I'm kicking myself for just spending $900 on freshening these things up just a couple months ago.

You wouldn't happen to want to trade them would you? I was supposed to get this same thing done to mine but they just suddenly stopped building engines and porting heads. I have the stage 2E heads. If I can find a buyer or work out a trade I will be interested. PM me.

I might, just depending on what is for trade.
These are excellent heads and I should have better pictures soon.

I finally got a chance to get the heads off the car...
These were taken right after I removed them.

You are correct. One of the finest set of heads out there. I have used these same heads with excellent success. That's a VERY fair price your asking.
