Help please!!!!!
I'm in the process of finalizing a deal on a set of 2007 ls2 heads with 5k on them. I have seen so many different opinions while doing a search from 2 different forums. My main concern is will these heads bolt directly to my 2000 ls1 c5 or 1999 Trans Am without any clearance problems. I also noticed the small green triangle on the heads, what is the significance of this? Please any info will help, ready to start the summer mod-fest!

From everything I have read, LS2 heads are a popular mod for an ls1. i have not read everything, but I've never seen anyone say they won't bolt right up. I think they are 243 casting which would be the same as the LS6....so what are you concerned about?

same as 243 heads, without sodium valve.... some do have a bit bigger combustion chamnber... 70cc.... great head for S/C application... lots of guys run them on their C5's.... no clearance issues etc...they claim to see between 25 - 35 hp net gain by themselves... put a bigger bump stick in there and some headers and they get lots more....I have a buddy running them...224/228 cam, long tubes, 799 heads, tune - 400 + RWHP...

Thanks! My main concerns was the clearance issues and the larger cc's. They are the 243 casting with the V shapes towards the bottom of the head. I' read that these make a few more ponies than the standard 243/799 casting. I don't know how true that is. The bumpstick will have to be down the line, possible a custom grind.
