sorry i haven't been on in a wile... i wasn't talking about my 1st gen, i have a 2nd gen engine for a project truck. thanks to everyone for the input looks like I'll o-ring the head for now if i pop the head gasket, I'll just surface the o- ring grooves out and fire ring it if the head doesn't get too thin. again thanks to all
