They might be hard to find. I'm thinking you will have to buy the complete engine just to get the heads. You can buy new castings pretty cheap. The 92 and LS3 will be in the 6.2 trucks , Cadillac Escolades, new Camaros and Vettes.

dude hit the forums here, they are for sale all the time, hit the camaro5 section or any section with ls3 engines, people get rid of them all the time after upgrading parts.

you could possibly call some local speed shops and see if they have any laying around from customer builds. most every speed shop I have been to you can find alot of great stuff just have the shop owner contact the owner of the parts and see if they want to sell them. but ls3 heads are on the sale section all the time in here, I just sold a set of CNC ones last month

I just received new LS3 heads with valves springs and retainers from Pace Performance for $629 (part number 12629063) That's a good price for brand new heads!

Doug G

Sorry to Hi-jack but somewhat relitive.. Ive seen mixed specs on the LS3 heads as far as the advertised combustion chamber cc size goes. Ive seen 68 and ive seen 70. Has anyone else? I just got my 12629063 heads (at cost btw) and measured them with washer fluid (low surface tension) and a graduated cylinder (with the spark plug installed and got exactly 68cc's. Intake was 263cc's and exh was 85cc's. Now I just came up with this method as an experiement and wanted my own basis to go by. Im planning on milling these babys down to get as much compression as I can run with 93oct but not sure how much is too much. PTV clearance shoud'nt be an issue for me due to my smaller cam im installing 224in.581in/236exh.601 exh. Question is if my Stock LS2 heads are 65cc's (?) whats the highest compression ratio I can get away with using LS3 heads on a stock LS2 on 93oct. I'll use thinner head gaskets too I dont care about that. And any suggestions on a timing chain? Billit,single roller,double roller,adjustable,nonadjustable,prestreched,stock, .... So many choices its overwelming..... lol sorry guys. This is my first perf LS build. Im a dealer tech and I'm just used to replacing factory parts with factory parts..
