:1zhelp: I want to replace my headgasket, not because I need to, but because I want to, as a preventive measure. I've searched, but I can't find any specific answers. If I use a Toyota headgasket and the ARP's, will I have to prep the head and or block?? if not can I just R&R the parts for the old ones??? Keep in mind I've not blown the stock gasket and the car has never overheated. Thanks for your time and help, really.:icon_smil
