CNE Posted February 19, 2007 Report Share Posted February 19, 2007 I talked to a guy Friday with a set of 6.0 heads that have been reworked with titanium oversized valves, comp. springs, ported, etc. He said he would take $650 for them. The springs I have been looking at are around $300. Sounds like a good deal to me, any opinions? I figure I could go ahead and pull the heads while I'm doing the cam swap.

gixxerrider Posted February 19, 2007 Report Share Posted February 19, 2007 LQ9 or LS2 heads Quote Link to comment Share on other sites More sharing options...
CNE Posted February 19, 2007 Author Report Share Posted February 19, 2007 Not sure, I think LQ9. I will find out more info. Quote Link to comment Share on other sites More sharing options...
CNE Posted February 26, 2007 Author Report Share Posted February 26, 2007 OK, update on the heads. They are LS2 6.0 heads, ported, polished, 3 angle valve job, decked, new performance springs, seals, oversized (not sure what size) titanium valves. He said he had all the paperwork from the machine shop, and will take $600. I'm kinda nervous about them but it sounds like a steal. Quote Link to comment Share on other sites More sharing options...
04CHASE Posted February 26, 2007 Report Share Posted February 26, 2007 what CC are the chambers? that is important it will determine you rcompression ratio Quote Link to comment Share on other sites More sharing options...
CNE Posted February 27, 2007 Author Report Share Posted February 27, 2007 Not sure about the chamber size, but I did look at the engine specs for my 6.0 and the LS2 6.0. Bore and stroke is the same, the compression ratio on one was 10.8, the other was 10.9 I think, so assuming they were stock heads from an LS2, it should be pretty close to stock CR other than the decking and I don't know how much they were cut.

04CHASE Posted February 27, 2007 Report Share Posted February 27, 2007 well it will up your cr ratio. i think the ls2 have the same pistons. so you will be a bit higher that will also increase power. i would suggest a cam while you have the heads off and maybe some long tubes. but you should see some big gains.

CNE Posted February 27, 2007 Author Report Share Posted February 27, 2007 I already have a cam, the one SSThunder had. Comp Cams 222/224, 566/568, 112 LSA, and long tubes. I will install the cam with the heads if I buy them. These heads will bolt up with no problem right? as far as the stock intake and all? I have to decide on the heads, and get gaskets and headbolts, if I do the heads. Quote Link to comment Share on other sites More sharing options...
04CHASE Posted February 27, 2007 Report Share Posted February 27, 2007 being your not boosted arp studs arent 100% necessary but i also beleive they have bolts that are a little cheaper. id buy some new stock head gaskets and you should be fine.

CNE Posted February 27, 2007 Author Report Share Posted February 27, 2007 I talked to my local performance shop guy (the one who has been helping me so far and will do my tune if I ever get the stupid cam in), about these heads. The guy with the heads says the springs are GM "hot cam" springs. I asked the shop guy about them and he said if the work was good, they were definatley worth the money but those springs were basically LS2 springs and would not be strong enough for my cam. He told me to find out what size valves, intake port size, CC, etc. and let him know and he could tell me more. If I will have to replace the springs in these heads to use them, I don't think I will mess with them at all. Quote Link to comment Share on other sites More sharing options...
