mean05 Posted November 17, 2008 Report Share Posted November 17, 2008 nothing wrong with heads that have been on a nitrous motor...my heads looked fine this weekend...intake runners actually stay clean with the spray...no oil build up or anything Quote Link to comment Share on other sites More sharing options...
hellbents10 Posted November 17, 2008 Report Share Posted November 17, 2008 I would have them checked out. At the least check the valve springs as they are more then likely hit if the owner was running a large cam with aggressive lobes. Quote Link to comment Share on other sites More sharing options...
mbarnes Posted November 17, 2008 Author Report Share Posted November 17, 2008 hes asking $550 for em. my concern w/ them is that hes says hes had them since 2001 or 2002 and only 23000mi??? im thinking alot of those miles are prob down the track. id hate to buy these things and take em to the local shop and find out theyre trashed. also does anyone have any specs on these heads. absolute is out of bus. thanks mark Quote Link to comment Share on other sites More sharing options...
hellbents10 Posted November 18, 2008 Report Share Posted November 18, 2008 Absolute did nice port work but they might need a valve job and springs at minimum. You labor operations could be from 50-500 depending on what the need done, like surfacing, valve job, valve guids..... Quote Link to comment Share on other sites More sharing options...
