DESCRIPTION: Chevy LS2 (243 Castings) heads off a 2007 TrailblazerSS. These heads were ported/polished by Greg Good in Houston, TX along with all the upgrades which include Rev Stainless Steel 2.055" Intake/1.60" Exhaust Valves, Patriot Performance Xtreme Springs (.660" lift), Titanium Retainers, Super7 locks and Viton rubber seals. You can see from below the great flow numbers from these heads. I know flow numbers are not the most important data when evaluating heads, but it is the only data I have. They were on my truck for about 7500 miles before I decided to return to stock. I also have a New set of LS1 Head gaskets that will go with them if you need them. Really need these to move. Please contact me if interested.

ALSO: If you would like a cam as well, I have this one still available and will do a package of $1200 shipped.

PICS:
I realize I could have spent more time cleaning them up, but it is what it is.
